CATALYST FILM FOR SOLID POLYMER ELECTROLYTE FUEL CELL, CATALYST SLURRY USED FOR IT, ITS MANUFACTURING METHOD AND FILM-ELECTRODE JUNCTION USING IT, AND SOLID POLYMER ELECTROLYTE FUEL CELL

摘要

PPROBLEM TO BE SOLVED: To provide a catalyst film for a solid polymer electrolyte fuel cell wherein the use efficiency of a catalyst is improved more than conventional. PSOLUTION: This catalyst film for the solid polymer electrolyte fuel cell comprises graphite, catalyst particles and an ion-conductive resin. The catalyst film for polymer electrolyte fuel cell preferably has a conduction supporting agent. With the catalyst film for the solid polymer electrolyte fuel cell of this invention, since arrangement of the catalyst and the ion-conductive resin in the catalyst film is optimized by using the graphite, the fuel cell with high use efficiency of the catalyst, excellent current collecting property, and thus a long generation life can be provided. And, it excels in low cost and handling property. PCOPYRIGHT: (C)2005,JPO&NCIPI
