Catalysts for PEM Fuel Cells (PEFCs): Platinum, Pt-Co and Pt-Ru alloys on Carbon

Our catalysts enable pollution-free, safe, lightweight power generation systems.

PEFCs provide high levels of power yet are small and light. They have become the focus of attention predominantly in connection with fuel cell electric vehicles (FCEV) and portable home power sources. There are high expectations for a new and environmentally-friendly power source utilizing the chemical reaction of hydrogen and oxygen. We have combined precious metal catalyst technology and electrochemical technology, both developed over long years of research, to successfully develop highly activated catalysts for cathode and CO-tolerant catalysts for anode of PEFC.
