CATALYST MATERIAL FOR FUEL CELL, CATALYST FILM, ELECTRODE-MEMBRANE ASSEMBLY, AND FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a catalyst material for a fuel cell or the like having high durability and catalytic activity for the purpose of improving utilization efficiency of catalyst particles.

SOLUTION: The catalyst material for the fuel cell contains carbon material, and polymer (X) is bonded on a surface of the carbon material through a bonding group having solvolysis resistance and heat resistant property. The polymer (X) has a group having solvolysis resistance and heat resistant property, and ionic functional group.
