Abstract
An electrolyte membranehaving different EW values in different regions provides durability comparable to that of an electrolyte membrane made of a single type of ion exchange resin (i.e., an electrolyte membrane having the same EW value in its entire regions). A process for manufacturing such electrolyte membrane is also provided. Two or more kinds of ion exchange resin membranesandhaving different EW values are disposed such that their edges overlap upon each other and are then placed on a lower dieof a hot press. An upper dieis moved closer to the lower dieto press the ion exchange resin membranesandwhile at least their overlapping regionis heated, whereby in the overlapping regionthe respective ion exchange resins are fused and mixed integrally. The adjacent ion exchange resin membranes are thus integrally bonded to each other in a stable manner, thus forming an electrolyte membrane
