Title:
膜-膜補強部材接合体、膜-触媒層接合体、膜-電極接合体、及び高分子電解質形燃料電池
Document Type and Number:
Japanese Patent JP5214471
Kind Code:
B2
Abstract:
A membrane membrane-reinforcement-member assembly, membrane catalyst-layer assembly, membrane electrode assembly, and polymer electrolyte fuel cell are provided, which are so configured as to ensure sufficient durability and a cost reduction in unit cells and be suited for mass production. To this end, a membrane membrane-reinforcement-member assembly (20) of a membrane catalyst-layer assembly (30) provided in an MEA (5) of a cell (100) has a polymer electrolyte membrane (1), a pair of first membrane reinforcement members (10a) and a pair of second membrane reinforcement members (10b) which members (10a), (10b) are embedded in the polymer electrolyte membrane (1) such that their main surfaces are not exposed therefrom. The first and second membrane reinforcement members (10a), (10b) are embedded in a parallelogrammatic fashion so as to overlap each other in the four corners of the polymer electrolyte membrane (1) when viewed in a thickness direction of the polymer electrolyte membrane.
