Fuel Cell Systems

Virtual Tour through our Fuel Cell Lab

In the research topicFuel Cell Systems, our work focuses on the following fields of work:

 

Characterization of Components, Cells and Stacks

 

Characterization of Systems and Peripheral Components

 

Development of Stacks and Systems

 

Production Research for Fuel Cells

 

Modelling and Simulation Performed on the Microscale up to the System Level

We support the development of membrane fuel cell systems in portable, stationary and mobile applications by characterizing single cells, cell stacks and entire systems. Furthermore, we test peripheral and cell components under extreme climatic conditions and with regard to their electrochemical resistance.

In addition to our research and development on fuel cell systems, we offer our customers characterization services in our laboratory center:

Center for Fuel Cells, Electrolysis and Synthetic Fuels

In the “Center for Fuel Cells, Electrolysis and Synthetic Fuels”, components and sub-systems for hydrogen technology are tested and characterized with scientifically based methods for applications in the fields of PEM electrolysis, PEM fuel cells (particularly for automotive applications), Power-to-Gas (PtG), Power-to-Liquid (PtL) and Power-to-Chemicals (PtC).

Characterization of Components, Cells and Stacks

Teststand for spatially resolved characterization of single cells with a multi-channel system with 68 potentiostats.
  • To investigate the cell design, for the material and component selection and the development of operating strategies, we perform spatially resolved measurements on segmented single cells with up to 68 channels and currents up to 790 A. For the characterizations, we make use of electrochemical impedance spectroscopy.
  • To investigate stack designs and develop operating strategies, we characterize fuel cells with currents up to 1000 A. We perform single cell monitoring in the cell stack measuring single cell voltage. For stack characterization on the system level, we trigger periphery components (purge valve, anode recirculation pump, cathode air supply, cooling, etc.).
  • Characterization of cell components and life time investigations on membrane electrode assemblies using electrochemical impedance spectroscopy, cyclic voltammetry, linear sweep voltammetry, limited current measurement, and CO stripping.
