Abstract:
1. A membrane-membrane reinforcing member assembly comprising: a polymer electrolyte membrane having a substantially square shape; a pair of first membrane reinforcing members disposed on one main surface of the polymer electrolyte membrane so as to extend along a pair of opposed sides, respectively, of four sides of said one main surface; and a pair of second membrane reinforcing members disposed on another main surface of the polymer electrolyte membrane so as to extend along a pair of opposed sides, respectively, of four sides of said another main surface, wherein: portions of the polymer electrolyte membrane at which portions the first membrane reinforcing members and the second membrane reinforcing members are disposed are concave; the first membrane reinforcing members and the second membrane reinforcing members are disposed such that main surfaces thereof are exposed, and the first membrane reinforcing members and the second membrane reinforcing members surround a peripheral portion of the polymer electrolyte membrane as a whole; the first membrane reinforcing members are disposed on the polymer electrolyte membrane such that exposed main surfaces thereof are located on a substantially same flat plane as said one main surface of the polymer electrolyte membrane; and the second membrane reinforcing members are disposed on the polymer electrolyte membrane such that exposed main surfaces thereof are located on a substantially same flat plane as said another main surface of the polymer electrolyte membrane.
