Abstract
Disclosed is a proton conducting polymer membrane formed by laminating a plurality of solid electrolyte membranes. This proton conducting polymer membrane is one prepared by laminating at least one layer of a solid electrolyte membrane formed by using a resin having a bis(perfluoroalkanesulfonyl)methide group in the chemical structure. This solid electrolyte membrane has a superior proton conductivity without transmitting the fuel (methanol or hydrogen).
