Fuel cells are one of the technologies that produce electricity with high efficiency and low emissions. They might offer society a way to a more sustainable energy production. In contrast to conventional combustion engines a fuel cell directly converts chemical energy into electrical energy.
All fuel cell types consist of anode/electrolyte/cathode as a repeating unit. These repeating units are connected in series to produce a useful voltage (a fuel cell stack). The repeating units are connected by so called bipolar plates or interconnects. The main purpose of the interconnect is gas distribution to the cells as well as electrical connection between individual cells.
The Fuel Cell Group (FCG) at Energy and Materials is mainly working on metallic materials for different types of fuel cells:
- Solid Oxide Fuel Cell (SOFC)
- High Temperature Polymeric Electrolyte Membrane Fuel Cells (HTPEM)
