Abstract
An electrolyte membrane is for forming an electrode having a desired shape with high quality and highly efficient productivity. Masking members (12 and 13) having holes (12a and 13a) bored in a desired electrode shape are attached to at least one side of an electrolyte membrane (11) for a fuel cell before an electrode is applied to the electrolyte membrane, in a self-adhering fashion or through a slight adhesive.
