Abstract
A fuel electrode catalyst for fuel cell excellent in CO poisoning resistance, an electrode/membrane assembly using the fuel electrode catalyst for fuel cell, and a fuel cell and a fuel cell system including the electrode/membrane assembly are provided. The fuel electrode catalyst for fuel cell comprises a platinum-ruthenium first alloy catalyst and a second alloy catalyst obtained by partially substituting ruthenium of the platinum-ruthenium first alloy catalyst by a metal lower dissolving potential than ruthenium. The electrode/membrane assemblycomprises three layers of a second alloy catalyst layer, a first alloy catalyst layer, and a ruthenium catalyst layerarranged in this order from a polymer electrolytic membraneside toward a gas diffusion layerside.
