Abstract:
1. A process for producing an electrolyte membrane comprising a first ion exchange resin and a second ion exchange resin having different ion-exchange group equivalent weight (EW) values that are successively arranged via a bonding region, the process comprising: disposing a first ion exchange resin membrane comprising the first ion exchange resin and a second ion exchange resin membrane comprising the second ion exchange resin such that interior edges of the membranes overlap to form an overlapping region while other portions of the membranes do not overlap; and integrally bonding the first ion exchange resin membrane and the second ion exchange resin membrane by heating and pressing at least the overlapping region to form the bonding region so as to melt and mix the first ion exchange resin and the second ion exchange resin at the overlapping region thereof, wherein the electrolyte membrane is disposed between a pair of electrodes, each electrode including a catalyst layer.
