ELECTRODE CATALYST LAYER FOR SOLID HIGH POLYMER FUEL CELL, ELECTRODE FOR SOLID HIGH POLYMER FUEL CELL, AND SOLID HIGH POLYMER FUEL CELL

摘要

PPROBLEM TO BE SOLVED: To provide an electrode catalyst for a solid high polymer fuel cell, capable of materializing high catalyst efficiency as a catalyst layer for a PEFC electrode, by making a proton conductor penetrate into pores formed by platinum carrying carbon black within a wide range, and to provide a high polymer fuel cell electrode using it, and a high polymer fuel cell using it. PSOLUTION: This electrode catalyst layer for the solid high polymer fuel cell is composed of a platinum catalyst, an electron conductor comprising carbon black, and the proton conductor, and the proton conductor in the catalyst is formed in an agglomerate formed by the carbon black or in the pores between the agglomerates. The catalyst layer is used for the electrode for the solid high polymer fuel cell, and for the solid high polymer fuel cell using the electrode. PCOPYRIGHT: (C)2005,JPO&NCIPI
