Resultater og erfaringer fra IEA Annex31 (22) – PEM fuel cells Informationsmøde, 18. Marts 2015 Hans Aage Hjuler 1 Danish Power Systems® Scope Hvorfor er vi her…? Hvad laver DPS? Formålet med IEA Annex 31 Resultater og vejen frem 2 Danish Power Systems® Askov wind power test centre Poul la Cour (1846-1908) Government funded centre The two test windmills are from 1891 and 1897 Direct Current Hydrogen storage Hydrogen light 3 Danish Power Systems® Energy in Denmark • Sustainable energy has been a major priority for several decades • No nuclear power • Windmill covers 39 % of the electricity production (2014) –and further 18 % is from renewable sources (biomass) • Grid reliability 99,997 % (world leading, second to Luxembourg only) • Siemens Wind Power (Denmark) and Vestas are world leaders in wind technology • High ambitions* in Denmark : – 50 % wind for electricity in 2020 – 100 % renewable energy for electricity and heat by 2035 – 100 % of all energy from sustainable sources by 2050 • Transportation issues are very difficult to solve • Fuels cells is expected to play a role in the future energy supply *Danish Government, October 2011: http://www.stm.dk/publikationer/Et_Danmark_der_staar_sammen_11/Regeringsgrundlag_okt_2011.pdf 4 Danish Power Systems® Integration of energy systems in Denmark Ressource Energy-system Sustainable energy Flexible and efficient (economy and energy) Import power Wind Energy service Low and stable prices Export el Power system Bio Gas CHP Elektrolysis Central Heatpump El-proces light, it etc. Decentral Heatpump.

HTPEM is high temperature polymer electrolyte fuel cells. DPS has focused on the actual single fuel cell unit (MEA) • DPS is an independent and privately owned company. • 10 employees and an international set-up • DPS is participating in Danish and European projects • Strong network with international and Danish companies, universities and organizations • Member of the Danish Partnership for Hydrogen and Fuel Cells • Member of IEA, Annex 22; Member of Sci. Committee, FCH-JU, EU • Member of EMIRI (incl. Steering Comm.) and NEW-IG, Brussels Danish Power Systems® 6 The role of DPS The strategy of Danish Power Systems is to develop and manufacture MEAs: • to produce MEAs with lower cost and higher performance than others • to increase the commercial business 7 Danish Power Systems® Technology The HTPEM technology has a number of very attractive features – fuel flexibility is a very significant advantages. It works at 160 °C. The high heat has advantages and can generate more electricity and be you for (absorption) cooling. It can work with pure hydrogen but also methanol, LPG, DME, diesel and more. Bio-methanol is CO2 neutral and compatible with existing infrastructure and traffic patterns of society today – thus: Access to cheap, clean, unlimited and renewable energy Implementation “today” From DoE Very limited cost of transition for society 8 Danish Power Systems® Simple HTPEM system Reformer Fuel cell Electricity Nat.

(600 cm2) Dapozol® 100 MEA Sizes Dapozol® Membrane Sizes M20 20 mm M40 40 mm M60 60 mm M80 80 mm Dapozol ® membranes are sold in sheets of 23 x 37 cm and are available in a number of thicknesses. Danish Power Systems® 18. marts 2015 IEA – Annex 31 PEM fuel cells 13 Danish Power Systems® Objectives Objective: To contribute to the identification and development of techniques to reduce the cost and improve the performance and durability of PEFCs and PEFC systems Operating Agent: D. J. Liu, U. S. Department of Energy, Argonne National Laboratory 14 Danish Power Systems® Tasks Subtask 1: Stack Materials –Membrane materials (new functional groups, cheaper membranes, composite membranes, high-temperature membranes, low-humidity proton conductors) –Electrode catalysts (lower Pt loadings, CO tolerance, lower-cost higher-performance structures, non-Pt materials) –Bipolar plates (new materials, improved manufacturability, lower costs) –Cells and stack assemblies (higher power density, low degradation, light-weight, lower cost, continuous fabrication techniques, >100ºC operating temp.) Subtask 2: System, Component, and Balance-of-Plant Issues End-user aspects (contaminants, humidification and thermal management, operating environments and duty cycles, rapid-start, durability, freeze-thaw cycling, and characterization of materials and components). System-level issues (systems analysis, stack/system hardware designs, fuel processing, and prototypes) Subtask 3: Direct Fuel Polymer Electrolyte Fuel Cells (e.g., Direct Methanol, Direct Ethanol, Direct Borohydride FC) Cell materials (anode and cathode catalysts, reduced precious metal loadings, MEA designs and processes for reduced fuel crossover, fuel impermeable membranes, anion-conducting membranes). Operating conditions (pressure, temperature, vapor versus liquid feed, fuel concentration, etc.). Stack and system designs and analyses (modeling, high-temperature operation, high power densities, high efficiencies, performance over duty cycles, etc.) 15 Danish Power Systems® Participants in Annex 31 Austria Denmark Finland France Germany Italy Israel 16 Japan Korea Mexico Sweden United States Danish Power Systems® Collaboration - 1 • Møder hvert halve år • Kombineres med konference (dansk forslag) • Alle deltagere holder indlæg om deres forskning- og udviklingsaktiviteter • I nogle tilfælde også resultater fra andre (IRD) • Udveksling af erfaringer • Besøg på verdens største MCFC anlæg i Korea • Virksomhedsbesøg hos Hyundai og testkørsel af fc bil 17 Danish Power Systems® Collaboration - 2 • Forsøg på at udvide kredsen til at omfatte flere lande (dansk forslag): o Tyrkiet, Spanien og Schweiz o Vanskeligt pga. manglende midler • Formidlingsaktiviteter • Booklet under overvejelse med beskrivelse af teknologier og partnere (dansk forslag – template herfra danner grundlag) 18 Danish Power Systems® Collaboration - 3 Ekstra aktiviteter…: • Samarbejde med IIE, Mexico om HTPEM (følges nok op med to studerende fra CBS) • Levering af materialer til japansk kunde - kunne ikke være gjort uden medlemsskabet af IEA 19 Danish Power Systems® Summary & perspectives: • IEA giver et vigtigt netværk indenfor H&FC • Administrationen kunne være mere effektiv • Deltagelsen har givet nye kontakter og nye kunder Danish Power Systems® 20 DPS International • Stack development (together with partners) 21 Danish Power Systems® Collaboration!
