Verbundelektrolytmembran, Membranelektrodenanordnung, Brennstoffzelle und Verfahren zur Herstellung selbiger

摘要

A method for manufacturing a composite electrolyte membrane including: a first folding process of folding a laminate (10A) obtained by laminating and integrating an electrolyte sheet (11) having an electrolyte as an electrolyte layer and a reinforcing sheet (12) having a porous polymer material as a reinforcing layer, so that a part of a surface of the laminate (10A) lies on another part of the surface; an impregnation process of impregnating the electrolyte of the folded laminate (10B) into the reinforcing layer; and a hydrolysis process of hydrolyzing the electrolyte impregnated in the laminate (10C).
