METHOD FOR MANUFACTURING MEMBRANE-CATALYST LAYER ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a membrane-catalyst layer assembly preventing bending of an electrolyte membrane when a base material sheet is peeled off, and to provide a catalyst layer transfer sheet used in the method.SOLUTION: A catalyst transfer sheet intermediate is used for manufacturing a membrane-catalyst layer assembly, and comprises: a base material sheet; and a self-adhesive electrolyte membrane support adhering to one surface of the base material sheet and forming an opening in a central part so as to make a frame shape.
