CATALYST LAYER FOR FUEL CELL, GAS DIFFUSION ELECTRODE FOR FUEL CELL, MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL, FUEL CELL, AND CATALYST LAYER FOR FUEL CELL WITH FILM BASE MATERIAL

摘要

PPROBLEM TO BE SOLVED: To provide a catalyst layer for a fuel cell constituted of a proton conductive electrolyte superior in reproducibility, excellent in moldability, and having a high proton conductivity in non-humidified state and catalyst particles, to provide a gas diffusion electrode for the fuel cell using the same, to provide a membrane electrode assembly for the fuel cell, the fuel cell, and to provide a catalyst layer for the fuel cell with a film base material. PSOLUTION: The catalyst layer for the fuel cell is constituted of the proton conductive electrolyte consisting of metal phosphate and phosphates and the catalyst particles. The metal phosphate is composed of a compound as represented by the following formula (1). Formula (1): MSB1-x/SBNSBx/SBPSB2/SBOSB7/SB. Herein, M, N are each a metal element, X is 0X0.5, M is one kind selected from a group of Zr, Cs, Sn, Ti, Si, Ge, Pb, Ca, Mg and Al, and N is one kind selected from a group of Al, In, B, Ga, Sc, Yb, Ce, La and Sb.
