CARRIED CATALYST FOR ELECTRODE AND ITS MANUFACTURING METHOD, ELECTRODE FOR PROTON EXCHANGE MEMBRANE FUEL CELL AND PROTON EXCHANGE MEMBRANE FUEL CELL

摘要

PPROBLEM TO BE SOLVED: To provide a carried catalyst for an electrode with improved resistance to poisoning against carbon monoxide and its manufacturing method, an electrode for a proton exchange membrane fuel cell and a proton exchange membrane fuel cell. PSOLUTION: The supported catalyst for an electrode and its manufacturing method, an electrode for a proton exchange membrane for a fuel cell and a proton exchange membrane fuel cell are such that a catalyst is supported on a conductive carrier, the catalyst includes at least platinum and nickel, an atomic ratio of the platinum and the nickel is 1:0.9 to 1:1.1, and a catalyst content to a whole supported catalyst is 30 weight % to 80 weight %. With this structure, the carried catalyst for the electrode improves a resistance to poisoning to carbon monoxide. PCOPYRIGHT: (C)2006,JPO&NCIPI
