Abstract:
1. An electrolyte membrane-electrode membrane assembly for a solid polymer fuel cell, wherein a gas diffusion electrode membrane formed with a quaternary base anion-exchange resin and an electrode catalyst is bonded to a solid electrolyte membrane formed with a quaternary base anion-exchange resin; at least a part of the quaternary base anion-exchange groups of the anion-exchange resin included in the gas diffusion electrode membrane and solid electrolyte membrane around the bonded interface is bonded each other via the quaternary base forming functional group of each ion-exchange resin and functional groups of a polyfunctional quaternarizing agent; and the anion-exchange resins included in the gas diffusion electrode membrane and solid electrolyte membrane are crosslinked via the polyfunctional quaternarizing agent.
