Abstract
A membrane-membrane reinforcing member assembly includes: a polymer electrolyte membrane (1) having a substantially quadrilateral shape; a membrane-like first membrane reinforcing member (10a) disposed on a first main surface (F10) of the polymer electrolyte membrane (1) to bend at a substantially right angle at a corner of the polymer electrolyte membrane (1) and extend along sides forming the corner; and a membrane-like second membrane reinforcing member (10b) disposed on a second main surface (F20) of the polymer electrolyte membrane (1) to bend at a substantially right angle at a corner of the polymer electrolyte membrane (1) and extend along sides forming the corner, and the first membrane reinforcing member (10a) and the second membrane reinforcing member (10b) are disposed to extend along four sides of the polymer electrolyte membrane (1) as a whole.
