Abstract
Laminates (A) that each have a catalyst layer and an electrolyte membrane are obtained either by disposing catalyst layers on one surface of each of a plurality of the electrolyte membranes, or by coating the catalyst layers with an electrolyte membrane forming composition. A membrane electrode assembly is then obtained either by layering the laminates (A) together with the electrode membrane sides facing each other, or by layering a laminate (A) and an electrolyte membrane (a) together such that one side of the electrolyte membrane (a) is in contact with the electrolyte membrane of the laminate (A) and then disposing a catalyst layer on the other side of the electrolyte membrane (a).
