PROBLEM TO BE SOLVED: To provide a catalyst for a polymer solid electrolyte type fuel cell having excellent electrode performance and carbon monoxide catalyst poisoning resistance, and a low manufacturing cost, and to provide a polymer solid electrolyte type fuel cell. SOLUTION: In a catalyst for a polymer solid electrolyte type fuel cell wherein platinum and two or more kinds of metals are supported on carbon powder carrier, platinum, ruthenium, and molybdenum are supported at the ratio of 1:(0.25-1)(0.2-0.5) (mole ratio). And platinum, ruthenium, and tungsten are supported at the ratio of 1:(0.25-2):(0.25-0.5) (mole ratio). When the particles of each precious metal are supported in such a condition that they are closer to form an alloy, these catalysts improve the carbon monoxide catalyst poisoning resistance of the catalyst more. |
