ANODE CATALYST FOR FUEL CELL, AND ANODE AND MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL COMPRISING SAME, AND FUEL CELL SYSTEM COMPRISING SAME

摘要

An anode catalyst for a fuel cell is provided to realize excellent catalytic efficiency, stability and fuel oxidation activity, and to improve the lifespan by avoiding a poisoning phenomenon caused by fuel. An anode catalyst for a fuel cell comprises an alloy of platinum with ruthenium and the alloy has a lattice parameter of 0.3840 nm-0.3866 nm. The anode catalyst is supported on a carrier, wherein the carrier includes a carbonaceous material or inorganic particles. The lattice parameter is measured by using CuKalpha radiation. The alloy comprises platinum and ruthenium in a mixing ratio of 8-50:92-50 on the weight basis.
