Joseph von Fraunhofer Prize 2009. Congratulations to Dr. Reinhard Lenk and Jörg Adler. This is the fourth prize for Yours, our institute (following transparent ceramics, directly integrated heating element in ceramic components [hot plate], and ultrasound disintegration of sewage sludge). Last but not least, I would like to address, on behalf of both Alexander Michaelis Dr. Voigtsberger and me, the most important strategic expansion of the Fraunhofer IKTS which was prepared in 2009. Due Dresden in March 2010 to the outstanding support of the headquarters of the Fraunhofer-Gesellschaft, we managed to merge the Hermsdorfer Institut für Technische Keramik HITK and IKTS within a very short period of time. Thus, the IKTS family has increased by 131 employees this year. I would like to give a special thanks to the Thuringian ministries which supported this merger extraordinarily well and raised enormous funds. Now, funds are also available to significantly expand the Hermsdorf branch. We would like to thank all the staff from Hermsdorf and Dresden that was involved in this integration process. Here, the collaboration has already proven to be successful. The merger was officially performed by a ceremonial act on the occasion of our colloquium “Ceramics Vision” on January 22, 2010. From now on, we will collaborate and offer our industry partners the best possible combined services. We want to further optimize and accelerate the technology transfer of our developments into industrial applications. We are convinced that together we are more apt to overcome the challenges of the future. We would like to invite you as our partners to avail of our outstanding services. First of all, we see ourselves as a service provider for the industry and are available for talks to identify common topics. 3 TABLE OF CONTENTS 2 FOREWORD 4 TABLE OF CONTENTS A PROFILE OF THE FRAUNHOFER IKTS 6 FRAUNHOFER IKTS IN BRIEF 8 ORGANIZATIONAL CHART 10 FRAUNHOFER IKTS IN FIGURES 12 BOARD OF TRUSTEES 13 THE FRAUNHOFER-GESELLSCHAFT RESEARCH ACTIVITIES AT FRAUNHOFER IKTS 14 DEPARTMENT: MATERIALS 16 LARGER SELECTION OF CERAMIC POWDERS FOR DEFECT-FREE GELCASTING 17 NANOSCALED HARDMETALS FOR CUTTING APPLICATIONS 18 MICRO RAMAN SPECTROMETER, AFM AND CONFOCAL LASER SCANNING MICROSCOPE 19 CERAMIC CORE-SHELL SPHERES AS ADSORBENTS AND CATALYSTS 20 CERAMIC PARTICULATE FILTERS FOR DOMESTIC WOOD STOVES 22 TESTING METHODS FOR DIESEL PARTICULATE FILTERS AND CATALYTIC CONVERTERS 23 LARGE-SIZED AND COMPLEX SILICON CARBIDE COMPONENTS 24 PRECURSOR-DERIVED INKS AND PASTES FOR PHOTOVOLTAIC APPLICATIONS 25 DEPARTMENT: PROCESSES / COMPONENTS 27 DEVELOPMENT AND MACHINING OF COMPLEX CERAMIC GEOMETRY 28 FLOWD – EVALUATION OF THE FILLING BEHAVIOR OF GRANULAR SYSTEMS 29 MANUFACTURING OF CERAMIC DENTAL PROSTHESES BY 3D PRINTING 30 MOLD FILLING SIMULATION AND NON-DESTRUCTIVE TESTING IN CIM 32 DEPARTMENT: SINTERING / CHARACTERIZATION 34 NANOPARTICLES – A CHALLENGE FOR CHARACTERIZATION 35 NEW DEVELOPMENTS IN METHODS AND TECHNICAL EQUIPMENT OF THE THERMOLAB 36 ELECTROCHEMICAL CORROSION OF SILICON CARBIDE MATERIALS 38 α-SIALON CUTTING TOOLS 39 MODELING OF MICROSTRUCTURAL EVOLUTION IN LPS-SILICON CARBIDE CERAMICS 40 SILICON NITRIDE MATERIALS WITH HIGH THERMAL CONDUCTIVITY 4 41 DEPARTMENT: MICRO AND ENERGY SYSTEMS 44 FRAUNHOFER FOUNDATION PROJECT – THE “ENERAMIC” MICRO FUEL CELL 45 INDUSTRIAL SOFC SYSTEM DEVELOPMENT 46 AUTOMATED HIGH-SPEED 3D STRUCTURING OF MULTILAYER CERAMICS 47 BIOETHANOL IN SOFC PARTIAL OXIDATION OF ETHANOL 48 NEW METALLIZATION TECHNOLOGIES FOR CRYSTALLINE SOLAR CELLS 49 LONG-TERM BEHAVIOR OF SOFC INTERCONNECTS 50 REACTIVE AIR BRAZE FILLER METALS FOR HIGH-TEMPERATURE APPLICATIONS 51 SOOT FORMATION AND ANODE REGENERATION IN SOLID OXIDE FUEL CELLS 52 HIGH POWER SOFC STACKS WITH CFY NETSHAPE INTERCONNECTS 53 DEPARTMENT: SMART MATERIALS AND SYSTEMS 55 NOVEL ALUMINUM-BASED HARD COATINGS BY CVD 56 ULTRASONIC TRANSDUCERS > 10 MHZ FROM CONCEPT TO SYSTEM 58 MANUFACTURING OF ACTIVE COMPOUNDS USING PLASTIC INJECTION MOLDING 59 ROBUST SENSOR / ACTUATOR MODULES BASED ON LTCC / PZT LAMINATES 60 PRODUCTION OF FUNCTIONAL CERAMIC FIBERS USING THE POLYSULFONE PROCESS 61 DEPARTMENT: ENVIRONMENTAL ENGINEERING AND BIOENERGY 63 STRAW – AN ATTRACTIVE SOURCE OF ENERGY 64 SEWAGE SLUDGE – AN INTERESTING CO-SUBSTRATE 65 DISINTEGRATION PROCESS – EFFORT AND BENEFITS FOR BIOGAS PRODUCTION 66 DISINTEGRATION OF SEWAGE SLUDGE SUCCESSFUL CONTINUOUS OPERATION 68 COMBINATION OF ELECTRICAL RESISTANCE TOMOGRAPHY AND CFD RETROSPECTIVE 70 EVENTS, EXHIBITIONS 75 PARTICIPATION IN TRADE SHOWS 77 COOPERATION IN GROUPS, ALLIANCES AND NETWORKS 82 NAMES, DATES, EVENTS 106 EXHIBITIONS 2008-2009 107 PLANNED EVENTS / TRADE SHOWS 2010 108 INFORMATION SERVICE 109 HOW TO REACH US 5 A PROFILE OF THE FRAUNHOFER IKTS FRAUNHOFER IKTS IN BRIEF The Fraunhofer Institute for Ceramic Technologies and Sys- Continuous production lines in the field of structural and tems covers the complete field of advanced ceramics, from functional ceramics basic research to applications.

The operating budget of 22.1 million euros equates to an increase of approximately 6 % as compared to last year. In total, 17.9 million euros were earned as external revenues – 1.2 million euros more than in 2008. With a total volume of 8.1 million euros, the industry revenues constitute approximately 45 % of the total revenues, and thus contribute to this result. The growth can be attributed to the successful acquisition of public revenues. Particularly the new record high of research funding by the Saxon ministries amounting to 4.2 million euros contributes to the increase of the operating budget. In 2009, 14.8 million euros were invested in the expansion of laboratories and pilot plants. 13.6 million euros of this sum were financed through external projects. Again, the success is due to the acquisition of 11.25 million euros in federal state funds for setting up a development center for energy efficiency systems in the field of fuel cells, thin-film photovoltaics, biomass conversion, thermoelectric generators (TEG), and storage media (lithium ion batteries). Developments of operating budget (in thousands of euros) at Fraunhofer IKTS for the budget years 2003-2009 Expansion of research basis The research field of energy and environmental technology continues to establish as innovation field for structural and functional ceramics. The application of ceramic technologies and components allows for the development of new system solutions ranging from biogas technology to photovoltaics. The expansion of test capacity for SOFC systems guarantees for future projects with system suppliers in the long-term. Both, existing partners and other companies benefit from these services and invest significant funds in Dresden. Various paste developments and the adaptation of printing methods 10 Personnel developments at Fraunhofer IKTS Number of employees 2003-2009, full-time equivalents Personnel structure on December 31 of each year ity systems research project. For this purpose, we invested in electrochemical test sites for battery systems up to 100 kW. Aside from the test equipment, the newly established test center provides equipment for the preparation and characterization of lithium ion battery materials. Fraunhofer's research programs significantly facilitate the generation of its own IP rights and thus, the long-term opportunity to acquire new industry projects. Personnel development Our project work led to an approximate 10 % increase of staff (scientists, graduates and technicians). This increase has been mainly realized by taking over doctorate students and parttime workers. At the same time, an increasing number of new doctorate students has been employed in cooperation with TU Dresden. In total, 50 doctoral theses will be supervised at the end of this year. As before, all apprentices who finished their apprenticeship in 2009 could continue their employment. By training apprentices at the IKTS, the quality of our laboratory work will be further improved. In 2010, mechatronic engineers are being trained for the first time. for solar cells have opened an industry-oriented field with absolute unique selling propositions for Fraunhofer IKTS. At Fraunhofer IKTS new solutions were developed to produce lithium ion batteries using thick-film printing techniques. By means of specially developed pastes, complete lithium ion batteries can be applied on substrate surfaces. Fraunhofer IKTS has specific know-how in the field of ceramic cathode materials which will be further developed in cooperation with industry partners. So far, we have paid special focus on micro systems technology, i.e. on performances in the range of some watt. Now, the technology is transferred to higher performances, and thus contributes to Fraunhofer’s electromobil- 11 BOARD OF TRUSTEES The president of the Fraunhofer-Gesellschaft has appointed the following people to the board of trustees at Fraunhofer IKTS: Dr. G.

Only one third is contributed by the German federal Locations in Germany and Länder governments in the form of base funding, enabling the institutes to work ahead on solutions to problems that will not become acutely relevant to industry and society until five or ten years from now. Affiliated research centers and representative offices in Europe, the USA and Asia provide contact with the regions of greatest importance to present and future scientific progress and economic development. With its clearly defined mission of application-oriented research and its focus on key technologies of relevance to the future, the Fraunhofer-Gesellschaft plays a prominent role in the German and European innovation process. Applied research has a knock-on effect that extends beyond the direct benefits perceived by the customer: Through their research and development work, the Fraunhofer Institutes help to reinforce the competitive strength of the economy in their local region, and throughout Germany and Europe. They do so by promoting innovation, strengthening the technological base, improving the acceptance of new technologies, and helping to train the urgently needed future generation of scientists and engineers. 13 DEPARTMENT: MATERIALS Dep artmen t h e a d : Dr. h ab i l .

Gelcasting is such a procedure 12 cm. starting with a suspension of dispersed ceramic particles which were poured into a mold followed by adsorption of the liquid component by controlled formation of a polymer network. In this way, the powder particles remain in their original state of Pore size distribution (mercury porosimetry) after burn out of organics at 800 °C dispersion and the liquid is removed from the gel body by a drying process. Fraunhofer IKTS has been engaged for a long time in gelcasting of corundum ceramics. For these ceramics the absence of defects in the case of very high density (e.g. after hot isostatic pressing) is obviously demonstrated through transparency. In the meantime the selection of materials has been extended to other materials like ZrO2, Y2O3, spinel and YAG. New monomer systems which react to particularly strong gels without increase of viscosity of the suspension allow greater opportunities for use of finer powders down to the nanoscale range. Figure 1 shows sample bodies after drying or sintering to densities between 97 and 99 %. The pore size distributions of the ceramic gel bodies burnt out at 800 °C (see diagram) demonstrate the high packing density of the obtained particle coordination. Powder morphology and chemical composition are crucial for a suitable interaction of the dispersing media, dispersing agents and gel-forming monomer.

R o l a n d Ho l k e It is the aim of the nanoHM project, which is funded by the German Federal Ministry of Education and Research (BMBF) Hardness of the new grades and commercial ultra-fine WC-Co hardmetals within the program “Nano for Production” and carried out by H.C. Starck (manufacturer of raw materials), FCT (sintering furnaces), Kennametal Technologies (hardmetal manufacturer), CemeCon (innovative coating systems), ASMEC (simulation and analytic), BMW (car manufacturer) and the Fraunhofer institutes IKTS and IST, to develop new cutting tools combining the extreme hardness and strength of nanoscaled hardmetals with the high wear resistance of nanoscaled coatings. Based on a nanoscaled tungsten carbide powder (A/m ~ 4 m²/g; dBET = 90 nm) made by H.C. Starck completely dense hardmetal parts were manufactured within the first year using methods appropriate for mass production. Research was based on earlier work of Fraunhofer IKTS. The hardness of the alloys with binder contents from 0 to 0.15 portions of mass which were manufactured by Fraunhofer IKTS was significantly higher than that of commercial ultra-fine hardmetal grades of the same binder content (see diagram). Milling and turning tools manufactured by Kennametal will now be coated by CemeCon and Fraunhofer IST using the newly developed nanoscaled coatings. The tools will be tested under laboratory and industrial conditions. Further research work of Fraunhofer IKTS is directed on a further reduction of grain size and an improvement of properties by optimizing raw materials and processing routes. 1 Cutting process. 2 Microstructure of a WC-10C hardmetal (dark: cobalt). 17 1 2 MICRO RAMAN SPECTROMETER, AFM AND CONFOCAL LASER SCANNING MICROSCOPE D r. Volk m a r R i ch te r, D i p l .-I n g . (F H ) S y l vi a Ri c hter At Fraunhofer IKTS three new analytical instruments were installed partly financed by the German Federal Ministry of Detection of single and multi-walled CNT Education and Research (BMBF): a confocal micro Raman spectrometer Raman Horiba LabRAM HR Vis (400 to 1100 nm), a confocal laser scanning microscope (CLSM) TCM SP5 from Leica Mikrosysteme and an atomic force microscope (AFM) Park XE-100. The coupling of the instruments allows the analysis and visualiztion of the same area of an object by means of different methods combining for instance information on topography and chemsitry. This may be used to investigate the distribution and effect of nanoparticles in organic material such as living cells, and to study the changes (like oxidation) the nanoparticles undergo. Lightweight particles such as carbon nanotubes (CNT) can also be detected in amorphous carbon or in organic material (see diagram above). In contrast to electronmicroscopical methods a time-consuming preparation can be avoided. A large number of ceramic materials like carbides, nitrides and oxides or different carbon materials were analyzed. The data gained for different materials, Surface of polycrystalline silicon crystal structures and impurity contents are used to build up a Raman data base. The data may also be used to detect and analyze particles in an organic environment. The atomic force microscope not only allows to gain data on topography (see diagram below) but also on electrical and magnetic properties and on heat conductivity in the nanoscale range. A wet cell and different scanning modes also allow the investigation of soft cells in a nutritive solution. 1 Raman spectrometer. 2 Laser scanning microscope. 18 Zeolite SiO2 1 2 μm CERAMIC CORE-SHELL SPHERES AS ADSORBENTS AND CATALYSTS Dr. I ngr id S c hulz , D r.

An efficient utilization of the active material became possible by developing Rupture strength of zeolite adsorbents adsorbents with a core-shell structure. The dynamic productivity of adsorption processes can be improved as a result of shorter diffusion path. The velocity of the diffusion process strongly depends on the size and geometry of pores in the active shell. At the same time sorbents must be strong enough to withstand rupture during the application. The use of silica sols cross-linked by polycondensation during processing provides a significant increase of the rupture resistance as compared to traditional inorganic binders. However, finest SiO2 particles cover the zeolite after drying and block the diffusion 0.1 of gases running through the pores of the zeolite which are 1 to 3 μm in size. Therefore, the addition of new pores is necessary using pore builders. Organic polymers (cellulose fibers) or complex compounds, which burn out in the temperature range up to 400 °C nearly without residues, proved to be proper. By combining strength-improving and pore-forming additives it was possible to improve the strength of the adsorbents and to simultaneously develop new diffusion channels assuring a bulk transfer performance comparable with zeolite adsorbents with traditional inorganic binders applied until now.

During their use all ceramic and catalytic components are subject to thermal, mechanical and chemical stress leading to damage of the components and degradation of their properties. At Fraunhofer IKTS post-mortem analyses are used to investigate characteristic properties of DOC and SCR catalysts as well as catalyzed and non-catalyzed DPF. Conclusions about the thermal and chemical degradation can be drawn by comparing new and aged substrates. For a defined thermal aging and testing of components for exhaust after-treatment a fully automated hot gas test stand is available. The test stand works at temperatures up to 1100 °C and uses mass flows up to 500 kg/h. Furthermore, it is combined with a soot aerosol generator. In addition to hot gas tests, soot loading regeneration and lifetime tests are possible. At Fraunhofer IKTS specific analytical methods are used for the investigation of exhaust components.

The manufacturing of complex components, in particular, is a special challenge in terms of manufacturing methods and economic aspects. The near-net shape concept Products and services offered frequently described already has limitations with simple geometries such as drilling patterns or channel structures with high aspect ratios and requirements on dimensional, geometrical and positional tolerances as well as surface quality. This is - Final machining of ceramic prototypes with standard tolerance up to IT 3 - Ultrasonic machining of hard-brittle materials mainly caused by insufficient manufacturing tolerances and surface qualities, which can be achieved by green machining, shrinkage during sintering as well as rough surfaces as a result of evaporation during sintering, particularly for nonoxide ceramics. Electrically conductive materials, e.g. hardened steels or hardmetals, can be shaped using electrical discharge machining. For ceramic materials, however, this method can only be applied in exceptional cases. Using wire spark erosion materials susceptible to corrosion can be damaged. For these reasons, a number of very modern CNC machines for surface, cylindrical and jig grinding as well as abrasive cutting and ultrasonic grinding are available at Fraunhofer IKTS. Ultrasonic grinding, in particular, is a very economical method in order to grind elements such as bores, deep holes or other programmable structures. Whenever tools are subject to wear during conventional machining, and thus high process forces cause depth damage in the material or hard-brittle materials cannot be machined economically anymore, ultrasonic grinding is an adequate solution.

Within this project foundations were laid for the development of materials, process and - Development of materials and processes for the generative manufacturing of ceramic components - Development of binder systems and powder modification for 3D printing of ceramics equipment. Until now the green density of ceramic parts made by 3D printing from powder has been too low to reach a high sintering density (> 95 %). Therefore, a solution has been worked out which combines the powderbed printing process with the printing of suspensions. Here, a suspension of nanoparticles is printed in a powder bed resulting in a higher and homogeneous packing density of the green body. The powder layer is consolidated by reactive interactions between the powder and the binder system at that point where the printing liquid (ink) contacts the powder. The binder system can be added to the powder or to the ink. For the zirconia powder TZ 3YE (Tosoh Corporation) a specific binder system was developed and adjusted ensuring a fast solidification of the respective powder layer and a good bonding between the powder layers. So, homogeneous green bodies with sufficient strength for handling can be generated.

On the one side, this tool is used to investigate the influence of constructive characteristics on the mold filling behavior, such as e.g. tempering channels, sprue design or the possibility to evacuate. On the other hand, the results of mold filling simulations can be verified by means of the test tool. For this purpose, the results obtained by mold filling experiments with different feedstocks at determined injection conditions are compared with the simulation results (Moldex3D®, Simpatec). Furthermore, the influence of varying injection parameters, sprue geometry as well as a vacuum on the filling behavior was studied.

On the other Simulation of flow behavior hand, computed tomography has been established as an essential tool for quality assurance in single and multi-component injection molding. It has to be emphasized that the components are tested in the green, debinded or sintered state without destroying them. This allows one to assign defects to single process steps. So, unnecessary process steps for defect components can be avoided and damaged components can be recycled.

The microstructure and the distribution of cations in the various sintering stages were characterized through preparation using ion beam methods and FESEM. In particular, the incorporation of the rare earth metal ions into the structure was measured by the Rietveld method. Analysis - Development of technologies and components based on Si3N4 or Sialon materials - Characterization of materials and components Content of incorporated rare earth metal ions versus theoretical content as a function of temperature of incorporation during sintering indicated that in the early stages of sintering the rare earth metal ion content in the α-Sialons is greater than the content in the equilibrium state at high temperatures (see graph). This could be the main reason for the equiaxial grain shape and the low fracture toughness values observed in the early years. It has two main consequences: Reproducible sintering and controlled adjustment of the α-Sialon content requires an excess of rare earth ions with respect to the ideal α-Sialon composition. The experimental results also showed, as was demonstrated for ß-Si3N4 using various methods, that a high rare earth metal ion content in the melt greatly stimulates anisotropic grain growth 1 Milling tool made of Sialon. and leads to higher fracture toughness values (lower grain 2 Microstructural image of Sialon. 38 YAG SiC Al2O3 1 2 MODELING OF MICROSTRUCTURAL EVOLUTION IN LPS-SILICON CARBIDE CERAMICS Dr. h ab il.

In addition, no data exist on the mobility of ions in the grain boundary phase. Hence, efforts to create a thermodynamically consistent dataset for the Si-Y-Al-O-N system have started in collaboration with TU Bergakademie Freiberg (TU - Thermoanalytical investigations up to 2400 °C and in diverse media - Specific microstructural analysis BAF, Prof. H.J. Seifert). Focus at Fraunhofer IKTS is on the experimental determination of liquidus temperatures, whereas TU BAF is concentrating on the creation and optimization of the thermodynamic dataset. The phase relations and the invariant points in the SiC-Al2O3Y2O3 system were determined to provide bases for the thermodynamic calculations. The investigations showed that the solubility of SiC in the melt is low. Figure 1 shows the evolution of the microstructure after solidification of the melt. Apart from information about the formation and the thermodynamic stability of the liquid phase, knowledge of the diffusion coefficients of the ions is necessary for modeling of the 1 FESEM image of solidified formation of surface zones/sinter skins.

By tailoring the composition and the microstructure Si3N4 materials with a thermal conductivity of up to 100 W/mK and dielectric strength > 25 KV/mm were costeffectively produced. These materials exhibit a four point bending strength of 600 to 800 MPa depending on the raw material and preparation route. Si3N4 components were produced by dry pressing and slip casting. The sintering process was optimized to reduce surface decomposition during sintering which is a prerequisite to use these materials as tapes. A water-based technology was developed which allows for the preparation of ceramic tapes with thicknesses of 0.3 to 0.8 mm. Substrates with dimensions of 120 x 90 mm² were prepared using optimized binder removal and sintering processes. These tapes have the flatness and roughness suitable for application in electronic devices. With the results obtained the foundations were laid for Si3N4 materials as substrates in power electronics and in other applications subject to high thermal and mechanical 1 Microstructure of a Si3N4 ma- stress. terial with high thermal conductivity. 2 Microstructure of Si3N4 green tapes (ion beam preparation). 40 DEPARTMENT: MICRO AND ENERGY SYSTEMS D epartmen t h ead : D r.

The device is based on SOFC technology. Thus, conventional propane gas can be used as a fuel to generate an electrical power of circa 100 W in a small and portable package. Applications for the generator can be found among camping and outdoor activities but also in the industrial sector. Fraunhofer IKTS is responsible for the complete system which is offered under the registered trade mark “eneramic”. Being manufactured by consequently using industrial-grade multilayer technologies, the active core of the system can be much smaller than comparable competitors. Numerous innovative materials and process solutions needed to be found and patent-protected, such as new metal-ceramic joints. The interaction of the system components was developed and optimized in a very short time frame by using fast and complex, yet capable simulation tools. The team itself is very interdisciplinary and cross-cutting. Beyond the technical system development, the team also addresses industrial product design issues such as safety, housing design and marketing. The very promising results so far prove in an impressive manner, how Fraunhofer IKTS connects highly integrated technological chains to system and market knowledge to achieve successful innovations with an outstanding customer value. 1 Micro SOFC stack in the test stand. 44 1 2 INDUSTRIAL SOFC SYSTEM DEVELOPMENT Di p l .-I n g.

Aim of the efforts is a simple, robust μCHP SOFC unit with a strictly limited number of sensors and actuators, low Temperature control of components along with load change maintenance requirements, easy assembling and with natural gas, electric power and heating as customer interfaces. To achieve this, the necessary fuel reforming utilizes cost and process-effective partial oxidation (POx). Further attention is directed to the development of control algorithms. It focuses on making fast parameter variation possible and on stabilizing the thermal behavior to improve temperature-change stability of sensitive system components. This goal is attained with degradation-resistant adaptive component controllers and model-based system controllers. Their implementation allows for the reduction of sensors by providing predicted process values. Within the framework of “Callux – Practical Tests for Fuel Cells in a Domestic Setting” which is supported by the German federal government the jointly developed fuel cell systems will enter field testing.

Thomas Pfeifer Ethanol is a well suited energy carrier for fuel cells as it has a Products and services offered high energy density, is non-toxic and simple to transport and store. If used in SOFCs, one major task is to produce synthesis gas from ethanol with a high percentage of H2 and CO. - Catalyst development, reactor design and dimensioning for reforming of biogenous raw materials Thermodynamic calculations showed that simple SOFC setups are possible with an ethanol POx reformer. Thermodynamic equilibrium for partial oxidation of ethanol was calculated with respect to carbon formation. It has been shown that with Thermodynamic equilibrium calculation for POx of ethanol for different λ and T air-to-fuel ratios above λ = 0.28 for ethanol (95 vol %) sooting does not occur for temperatures above 700 °C. Currently, the most important task is to identify effective, long-term stable catalysts for partial oxidation of ethanol. Experiments with low-cost base metals like nickel, copper, iron and cobalt on different supports showed great promise for ethanol conversion. The catalyst samples were characterized with optical emission spectroscopy (ICP-OES), surface analysis based on Brunauer, Emmett and Teller (BET) and scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX). It is the goal of the preparative work to develop a thermally stable catalyst with a high dispersity of the metal on the carrier surface. The carbon formation on the surface was reduced by modification of the surface with lanthanum. The rate of yield of H2 and CO was increased with suitable active components. Now, by-products are to be detected using gas chromatography and mass spectroscopy with the aim to increase the selectivity of the catalyst. 1 Foam ceramics with coating. 2 Reactors for reforming. 47 1 2 NEW METALLIZATION TECHNOLOGIES FOR CRYSTALLINE SOLAR CELLS D r.

Examples are mask-based printing technologies (ultra-fine-line screen printing, stencil printing, gravure printing) as well as digital printing I-U characteristic curves of test cells and microstructure at the Si/metallization interface vs. firing temperature technologies (aerosol and ink-jet printing). Minimal printable lateral dimensions are currently in the range of approx. 40 μm for mask-based printing technologies (single pass). By digital printing technologies minimal lateral dimensions of approx. 25 μm can be achieved (multiple pass). The properties of the pastes/inks have to be tailored for each printing technology (e.g. solid content, structural viscosity, thixotropy). Further material adaptations are related with e.g. optimized printing resolution and electrical performance (contact and finger resistance, efficiency). For advanced cell concepts the metallization pastes/inks have also to be tailored (e.g. for selective emitter concepts). The composition of the tailored materials for solar cells plays an important role. Fraunhofer IKTS is able to develop and adapt all paste components (e.g. glasses with specific wetting and reaction behavior, metal powders with appropriate particle size distribution, organic binder system). The following step of process optimization (printing parameter, thermal processing) is part of each development.

At present FeCr alloys are the most preferred materials for SOFC interconnects. For evaluating the materials in terms of oxidation resistance samples of different ferrite alloys were prepared and stored at 850 °C for more - Characterization of materials and metal-ceramic composites in the high-temperature range - Development of ceramic materials for protecting and contact layers in SOFCs than 12,000 h in air. Because of oxidation an oxidation layer grows on the surface of the alloy the thickness x of which increases with the time t according to the law x=k∙tn (k – growth Increase in mass of different alloys at 850 °C in air constant, 0 < n < 1). The increase of the layer thickness on the metal substrate correlates with the increase of the sample mass. Comparing different steels it was found that the alloys, the oxidation rate of which increases with the time, are not long-term stable for an application over 20,000 h (ZMG232 alloy in the diagram). By analyzing polished cross-sections it was determined that the change of the oxidation curves is in accordance with the change of the oxidation mechanisms in the alloy. An accelerated increase in mass indicates that the Cr content in the alloy falls below the critical concentration of about 15 wt % as a result of chromium diffusion and evaporation. The oxidation does not only take place on the surface of the metal substrate, but also in the base material of the alloy (“breakaway oxidation”). The experiments showed that the onset of the “breakaway oxidation” does not only depend on the structure of the alloy, doping elements, temperature and storage duration, but also on the geometrical shape of the surface which is in contact with the oxidizing atmosphere. All these criteria are very important for the development of the interconnect design. 1 Cross-sections of the samples after 12,000 h storage in an oxidizing atmosphere. 49 1 2 REACTIVE AIR BRAZE FILLER METALS FOR HIGH-TEMPERATURE APPLICATIONS D ipl. - Ing.

An attractive alternative is given by reactive - Analysis and characterization of interfacial reactions in joints braze filler metals containing active components that allow under application-oriented conditions brazing processes in air. The Fraunhofer IKTS develops such reactive braze filler metals based on Ag and CuO as an activating component. By varying Thickness of a reaction layer between alloy and braze after storage in air at 850 °C the CuO content the wetting behavior of these brazes on ceramic surfaces can be adjusted. These reactive braze filler metals can be used for example to join solid ceramic electrolytes made of doped zirconia with metallic interconnectors made of Crofer 22 APU or ITM-LC for the application in high-temperature fuel cells (SOFC) or sensor elements. Joints in high-temperature fuel cells must withstand high operating temperatures up to 850 °C and harsh environments such as a dual atmosphere and electric load for the whole lifetime of the fuel cells. Therefore, the development of these brazes must regard the behavior of the brazed joints under process-oriented conditions. Figure 2 shows a typical microstructure of a joining zone with a reaction layer of 5 μm thickness consisting of a Cr-Mn-Cu oxide on the metal side, which is formed during the brazing process. Analyses of aged joints (up to 800 h at 850 °C) reveal that the growth of this reaction layer according to a saturation mechanism is the most significant change in the joining 1 Induction brazing unit. zone which is not thicker than a free oxide layer on this alloy. 2 REM image of the joining zone. 50 1 2 SOOT FORMATION AND ANODE REGENERATION IN SOLID OXIDE FUEL CELLS M . Sc. S e na K a v ur ucu S ch u b e rt, Dr. M i h a i l s K u snez off As solid oxide fuel cells can be operated with various fuels they are very attractive for different applications. In many of Impedance spectrum of a single cell stack with soot formation at 650 °C and with regeneration at 850 °C these applications carbon containing gases are used as fuel which can cause soot formation in the cells especially during heating up and cooling down of the SOFC stacks. Experiments were performed with single cell stacks in order to investigate the influence of temperature, heating rate and gas composition on the carbon formation mechanisms. The cells were tested under real operating conditions with a simulated natural gas reformate. According to thermodynamical calculations, the carbon monoxide content in the gas was found to be responsible for carbon formation in the stack which occurs below 700 °C. With increasing temperature, carbon formation can increase due to the presence of hydrocarbons (CxHy). However, it is shown that it is possible to completely regenerate the CO contaminated stack under electrical load at 850 °C. As soon as current is drawn from the stack the water and carbon dioxide content increases in the anode atmosphere positively influencing the carbon gasification reaction. The studies with different types of hydrocarbon such as acetylene (C2H2), ethene (C2H4), and butane (C4H10) show that carbon formation is also possible at high temperatures. The experiments were carried out under system-like conditions. From it, efficient strategies can be deduced for carbon-free and stabile operation processes of stacks in SOFC systems. 1 Soot formation in the stack Products and services offered under extremely disadvantageous operating parameters. - Testing of SOFC stacks and MEAs in terms of soot formation with different operating parameters 2 Soot formation on the outer anode surface. 51 1 2 HIGH POWER SOFC STACKS WITH CFY NETSHAPE INTERCONNECTS D r.

Typical CHP systems on the basis of internal combustion engines (Diesel, Otto, Stirling and gas turbines) generate electricity with low CHP coefficients and mainly produce heat (approx. 2/3). The efficiency of a SOFC stack can amount to 80 %. Electrical efficiency and electrical power of a SOFC stack are essential for its profitable operation. The highest power density and electrical efficiency can only be achieved with planar SOFC stacks. Electrolyte supported cells with 10SCSZ electrolytes allow power densities of more than 500 mW/cm². On account of the thermomechanical properties this potential can only be used in stacks with chromium based (especially CFY from Plansee SE) interconnects. High power, robustness and long-term stability are essential for stationary SOFC systems. In order to fulfil these requirements Fraunhofer IKTS designs in close collaboration with Plansee a new stack design with higher active area, simple cathode contact, external cathode manifold and optimized interconnect layer. The verification of the new design confirmed that the stack performance can be scaled to higher active areas. Current development is focused on long-term stability, temperature cycling, reliability of SOFC stack assembling, and system integration.

For this reason, the Fraunhofer IKTS is engaged in the modification of state-of-the-art layers as well as in the development of new coatings. Among them are composite layers consisting of aluminum chromium oxide (Al,Cr)2O3 and chromium carbides CrxCy (Fig- - Development of coatings and deposition of prototype coatings - Complex characterization of coatings Flank wear mark vB versus cutting distance for milling 42CrMo4V steel ure 1). The deposition of layers with chromium contents of up to 13 at % is possible. CVD composites generated in this way show a high hardness of 27 GPa and a high wear resistance. At milling 42CrMo4V steel the novel composite coating has a lower flank wear than a state-of-the-art alumina coating (see diagram). The CVD process is based on a newly developed precursor consisting of ternary chlorides. By systematic process optimization coatings with different chromium contents as well as multilayer coatings were deposited. The development of fine-grained alumina coatings is another focus of IKTS research (Figure 2). In addition to the thermodynamically stable α-phase (corundum) alumina forms a series of polymorphs. At Fraunhofer IKTS a coating was developed consisting of a phase mixture of γ-Al2O3 and θ-Al2O3. This layer shows a nanocrystalline structure with grain sizes between 50 and 150 nm as well as a Vickers hardness of up to 28 GPa. 1 Cross-section of a composite Such values belong to the highest which have been achieved coating consisting of (Al,Cr)2O3 for alumina coatings.

Array designs can be prepared by using the related screen print layout, appropriate fiber arrangement or post processing with a wafer saw. Characterization The complex functionality of ultrasonic transducers requires substantial tests and measurements during manufacturing and final inspection. Electrical measurements represent relatively simple methods, which are very useful for the characterization of performance data during processing, but they are very limited to predict acoustical properties. Laser vibrometry can be used for vibration analysis and is established in our laboratory for frequencies up to 20 MHz. Sound field analyses as part of final inspection is inevitable, as it is the only way for proving the operational performance. Different methods, for example pulse-echo measurement, transmission measurement as well as sound field measurements with help of a hydrophone within a water basin are available.

In cooperation with IfWW of TU Dresden, the process which was originally used for the production of filtration membranes and hollow fibers, is further developed at Fraunhofer IKTS in order to spin functional ceramic fibers with specific custom-designed qualities. Within the SFB/TR 39 project, e.g., piezoceramic fullfibers with a very small porosity are developed which are finished to piezoceramic fiber composites with a duroplastic or thermoplastic matrix. These elements can be integrated in lightweight structures to realize smart lightweight elements with integrated sensors, actuators, generators or ultrasonic transducers. Another field of research is the development of ceramic fibers which can be finished to nonwovens and used as catalyst supports of high mechanical resistance for high-temperature processes. For this purpose, fibers with a huge active surface are produced, processed to permeable non-woven structures with almost no restrictions for geometry, and subsequently sintered. Then, the structures are coated with a catalytically active material. The catalytic activity is characterized in a special reformer test site. Figure 1 exemplifies the composition of the combustion gas for an ethanol reforming process in which the newly developed coated zirconia fibers and a commercially available honeycomb structure were tested.

At the same time huge amounts of nutrients and trace elements bound in municipal sewage sludge are destroyed by thermal disposal. Long-term experiments on quasi-continuous fermentation of corn silage verified that only processes with adequate supply of trace elements (addition of manure [R2] or liquid waste activated sludge of a wastewater treatment plant [R1]) can be operated efficiently over a long period. Process of laboratory fermentation The addition of sewage sludge (liquid or dried) had the same long-term stabilizing effect on fermentation of corn silage as commercial trace element products. That is why the evidence in principle for a useful combination of sewage sludge and agricultural biogas production could be generated. Further advantages (e.g. increase of fertilizer value of outlet products) as well as possible risks (e.g. contaminants in sewage sludge) have to be studied systematically before the method is transferred into practice.

The use of commercial enzymes and high-power ultrasound as disintegration method are to be analyzed to evaluate the effectiveness. Future development activities should concentrate on a substrate-oriented and energetic improvement of existing size reduction technologies. Another focus is on biological hydrolysis in order to use the disintegration potential of plant biocenosis. The target-specific application of disintegration processes can significantly increase the economic efficiency of biogas plants because of a better utilization of the input substrates and an improvement of the reaction conditions in the digester. The disintegration of the input substrates leads to a decrease in viscosity of the digestate and a reduction of the floating and sinking layers which improves the mass and heat transport in the digester. This results in a reduction of internal consumption of electricity and operational disturbances, for example by clogging. Own studies show that a mechanical size reduction of the input substrates, especially with a high content of per- Funded by the European sistent substances (e.g. lignocellulose), leads to a considerable Union and the Free State of 1 SVC screw press PP 7 RL. improvement of the anaerobic degradation.

It contributes to an ecological and economical operation on waste water treatment plants in Germany and abroad.

Despite a PC high power input of the impeller homogeneity is often not achieved in the biogas reactor. Inappropriate stirrers and a disadvantageous height-to-diameter ratio of the reactor are considered to be the causes for inhomogeneity.

A further improvement of the mixing quality, described by homogeneity, can be achieved by the pre-treatment of the substrates (see diagram).

Many partners use the fast access to the research infrastructure of the Fraunhofer-Gesellschaft. The spectrum ranges from the analysis and characterization of materials to the exclusive development project for large-scale production. The institute and the ceramic manufacturers draw a bow from raw materials to systems and from prototypes to series components. TASK GmbH supports the Fraunhofer Demonstration Center AdvanCer in conducting its workshops and training courses by providing the required practice-relevant and market information. Close collaboration between the researchers of the Fraunhofer Demonstration Center AdvanCer and the ceramic manufacturers has enabled users to quickly realize their ideas. Thus, a project forum for small and medium-sized companies has developed facilitating contacts to project initiators and research institutes. By visiting Ceramics Meeting Point within the framework of numerous events taking place at Fraunhofer IKTS more than 2000 visitors could inform about ceramic product innovations and manufacturers in 2009. Main focus of the external industrial exhibitions under the motto “Innovation by cooperation“ was on the Hannover Messe with a booth size of 300 m² and the Ceramitec with a booth size of 400 m².

Grit Michael For a moment, time seems to be standing still and allows the viewer to be a witness of this change. The paintings of Moritz Renner show the beauty of the dilapidation of brown-field sites which are recaptured by nature. In his oil paintings the artist successfully draws attention to the engineering performance and the excellent architecture of past industrial culture as well as their integration into newly emerging countrysides. The artist provides a good contrast to these paintings by means of his portrait of modern architecture showing our institute building. It has changed during the past years as it was continuously extended. He captures the current appearance of the building in his artwork which can be visited at Fraunhofer IKTS soon. A leap forward in time on the occasion of the 200th anniversary of Goethe’s and Runge’s theory of colors was made in the exhibition “Photography – Sense – Thesis“ by Manara Grund and Jochen Rohde which was embedded in the program “color contino“ with the TU Dresden, ALTANAGalerie and the SLUB Book Museum. 1 Jochen Rohde 2003: Chakra Similar to Moritz Renner, for Manara Grund space and time portrait Con moto.
