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

DPS facts
•
DPS produce and develop the energy efficient HTPEM technology
which utilizes renewable fuels. 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

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

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

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.

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.)

• 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

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)

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
