MEMBRANE-MEMBRANE REINFORCING MEMBER ASSEMBLY, MEMBRANE-CATALYST LAYER ASSEMBLY, MEMBRANE-ELECTRODE ASSEMBLY, POLYMER ELECTROLYTE FUEL CELL, AND MANUFACTURING METHOD OF MEMBRANE-MEMBRANE REINFORCING MEMBER ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To prevent a membrane-membrane reinforcing member assembly of which durability is improved by preventing breakage of a polymer electrolyte membrane more surely.

SOLUTION: The membrane-membrane reinforcing member assembly includes the polymer electrolyte member 1 and a first membrane reinforcing member 10a formed in a membrane shape or in a plate shape and then formed so as to have an opening 11, and arranged so that one main surface 13 thereof comes into contact with the one main surface in the polymer electrolyte membrane 1. In the assembly, a chamfered part 15 is formed so that at least a part of the edge part 11a of the opening 11 of the first membrane reinforcing member 10a is connected to the main surface 13.
