ELECTRODE FOR FUEL CELL AND MANUFACTURING METHOD OF SAME, MEMBRANE-ELECTRODE ASSEMBLY AND MANUFACTURING METHOD OF SAME, AND SOLID POLYMER FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a fuel cell enhancing adhesion of a gas diffusion layer comprising carbon paper or a carbon cloth with an electrode catalyst layer containing catalyst particles and a polymer electrolyte and generating no peeling off or no cracks of the electrode catalyst layer; to provide a membrane-electrode assembly (MEA) equipped with the electrode for the fuel cell; and to provide a polymer electrolyte fuel cell equipped with the membrane-electrode assembly.

SOLUTION: The electrode for the fuel cell is formed by forming a binder layer (a buffer layer) containing a thickening agent on the gas diffusion layer, and laminating the electrode catalyst layer containing the catalyst particles and the polymer electrolyte on the binder layer (the buffer layer).
