FUEL CELL SYSTEMSPROJECTS. PRODUCTS. PARTNERSHIPS.
RESEARCH FOR THE MARKET
Fuel cells supply electricity and heat with zero-emissions
and thus will be an important building block of a sustainable
energy economy. The Fuel Cell Systems group at the
Fraunhofer Institute for Solar Energy Systems ISE in Freiburg
supports and advises customers with interdisciplinary know-
how and comprehensive services ranging from basic research
and development to product commercialization.

High energy density and long operation time, ease of
use and fast charging, reliable off-grid energy supply,
wireless and environmentally-friendly operation are
some of the characteristics that make fuel cells attractive
for many markets.
You can use our IP either within the framework of a
cooperation or by obtaining the licenses.
Many valuable impulses in the system technology have
matured through the intensive cooperation with the
University of South Carolina (USA), the National Science
Center for Fuel Cells as well as with the Fraunhofer
Center for Sustainable Energy Systems CSE (USA), a
joint venture of Fraunhofer ISE and MIT in Boston.

REFERENCE PROJECTS
Miniature Energy Giants in Series Production
In cooperation with FWB Kunststofftechnik, we are
carrying out several bilateral and cooperative projects,
which include other partners from medium-sized
companies, industry and academia. The goal is to
develop competitive micro fuel cells for the industrial
series production.
The task: Develop a cost-effective DMFC in injection
molding with a power from 0,1 bis 10 Wel with high
energy density and a simple system technology
The technology: Planar fuel cells for air-breathing
operation, active and passive methanol supply
Range of services: Project planning and multi-stage
implementation, development of cell design and system
architecture, specification and selection of components,
conducting and analysing lifetime tests under varying
climate conditions
Milestones: start in 2005, commercialization planned
for 2011 in the markets of GPS-based container tracking,
off-grid sanitary devices and sensor technology
The basis of the development is the wide-ranging and
international patent portfolio of our Institute. The
Institute’s involvement in international standardization
committees as well as its cooperation with the VDE-
Institute for testing fuel cells provide the prerequisites
for product development according to international
standards.
International Researchon System Technology
Since 2009, and within the framework of an inter-
national consortium of five German and five Canadian
research institutes, we continue to improve the
understanding of the physical phenomena related
to water management in PEM fuel cells.
The task: optimizing the water management of
membrane fuel cells on the micro and macro scale
through new materials and designs as well as through
innovative operating strategies
Research content: Investigating the influencing
factors of the materials and surfaces in membranes,
electrodes, microporous layers, gas diffusion layers
and bipolar plates with respect to the diffusion,
convection and storage of product water
Milestones: start in 2009, building up a worldwide
unique scientific cluster, carrying out and documenting
experimental analyses and describing the physical and
thermodynamic effects
Founded on scientific expertise, improvements on
the components, the cell and stack design as well
as the operation are being continually carried out.
Thus, the reliability, efficiency and the lifetime of
the fuel cell system are constantly improved.
