Fuel Cells

Fuel Cells (FC) convert the chemical energy stored in the fuel directly into electrical energy, making them a very efficient and sustainable power source. For automotive applications, the Polymer Electrolyte Membrane Fuel Cell (PEMFC) with hydrogen as a fuel has proven its readiness for action. PEMFCs split hydrogen into protons at the anode, which travel through the electrolyte and react with oxygen from the air to form water at the cathode. The electrons are passed through an external load (e-motor) or storage (battery).

Durability and power density goals necessitate further research and development. A system test bench with battery simulator for the investigation of fuel cell stacks including the required auxiliary devices (Balance-of-Plant: BoP) has been developed at the institute. The aim is to investigate the important water management of the fuel cell under the changing loads typical in vehicle operation. In addition to experimental investigations, sophisticated simulation tools such as 3D-CFD simulation can be used to make internal processes accessible and thus drive development forward.
