<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a PEFC electrode in which a platinum metal exists mainly in the interface of the surface of carbon particles and ion cluster portion of a cation exchange resin and in which the platinum metal in the PEFC electrode is increased and the utilization factor of the platinum metal is improved by solving a problem that binding force between the surface of the carbon particles and the cation exchange resin is not sufficient. <P>SOLUTION: The manufacturing method of a PEFC electrode includes a process in which a mixture containing carbon particles and a cation exchange resin is heated at a temperature of glass transition temperature or more and decomposition temperature or less of the cation exchange resin, and then, cations containing a platinum metal element are adsorbed to the cation exchange resin contained in the above mixture, and then the cations are reduced. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
