PASTE COMPOSITION FOR FORMING CATALYST LAYER, AND TRANSFER SHEET FOR MANUFACTURING CATALYST LAYER-ELECTROLYTE FILM LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a transfer sheet for easily manufacturing a catalyst layer-electrolyte film laminate, and a paste composition for forming a catalyst layer to manufacture the sheet.

SOLUTION: The paste composition is a paste composition for forming a catalyst layer in which (2) a hydrogen ion conductive polymer electrolyte and (3) a solvent are blended into (1) an aqueous dispersion of catalyst carrier carbon particles, the solvent is at least one kind of solvents selected from a group composed of propylene glycol, ethylene glycol, diethylene glycol and N-methylpyrrolidone. In the sheet, a plurality of catalyst layers are formed at prescribed intervals on one surface of a base material. The transfer sheet is manufactured by forming a coating film composed of the paste composition on at least one surface of the base material.
