Highly Durable Oxide-based Catalysts for Polymer Electrolyte Fuel Cells (DuraCAT)
Scope of projectThe project aims at developing stable Polymer Electrolyte Fuel Cells (PEFCs). In PEFCs the electrochemical reactions, viz. the hydrogen oxidation reaction (HOR) and the oxygen reduction reaction (ORR) take place on the surface of typically Pt-based catalysts at the so-called three-phase boundary. Today, improving the performance of the cathode of PEFCs, where the ORR takes place, is probably one of the most urgent requirements because both the catalyst kinetics and its corrosion stability are clearly insufficient to make PEFCs cost competitive devices for automotive and stationary applications.
In short, this proposal is a multi-level approach towards the development and the understanding of high durable cathode catalysts for PEFCs on the basis of doped metal oxide supports. Thus, it requires to bring together highly specialized groups from different fields.
