New CO tolerant anode catalysts for reformate type polymer electrolyte fuel cells are proposed that are superior to state-of-the-art Pt-Ru metal alloy catalysts. Composite catalysts based on platinum and organic metal complexes were fabricated by a new procedure where platinum precursor, metal complex and carbon black powder were mixed and then heat-treated in Ar atmosphere at 400°C. Catalysts were evaluated in the anode half cell or single fuel cell at 70°C with H2 containing various levels of CO. Compared with commercial Pt-Ru/C catalysts, new anode catalysts proved to be very promising both in initial and long term performances.
