ELECTRODE CATALYST LAYER FOR FUEL CELL, MANUFACTURING METHOD OF THE SAME, FILM ELECTRODE ASSEMBLY BODY USING ELECTRODE CATALYST LAYER FOR FUEL CELL, FUEL CELL, AND VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an electrode catalyst layer capable of obtaining excellent power generation performance at a low humidity environment (for instance, 40%RH)SOLUTION: The electrode catalyst layer for a fuel cell contains an electrode catalyst using a catalyst carrier of high specific surface area (BET specific surface area exceeds 1000 (m/g carrier)). Sulfonic group density is greater than or equal to a predetermined value.SELECTED DRAWING: None
