ELECTRODE FOR POLYMER ELECTROLYTE FUEL CELL, METHOD FOR MANUFACTURING CALCINED FILM OF POLYMER ELECTROLYTE FUEL CELL, METHOD FOR USING ELECTRODE OF POLYMER ELECTROLYTE FUEL CELL, AND POLYMER ELECTROLYTE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a polymer electrolyte fuel cell, the electrode suitably maintaining a wet condition of a solid polymer film by securing suitable water retention characteristics.

SOLUTION: In the electrode 1 for the polymer electrolyte fuel cell made of a gas diffusion layer 2 with conductivity and ventilation characteristics and a catalyst layer 3 including a catalyst 6 carried by a catalyst carrier, the gas diffusion layer 2 is provided with cup-stack type carbon nanotube at a designated length, and a calcined film in which conductive fillers shorter in length than the cup-stack type carbon nanotube are mixed. The catalyst 6 is carried on the calcined film functioning as a catalyst carrier.
