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).
Claims11
A proton conducting polymer membrane comprising:
- a first solid electrolyte membrane containing a resin having a bis(perfluoroalkanesulfonyl)methide group in the chemical structure, and including a first and second surface, and
- a second solid electrolyte membrane containing a resin having a sulfonic acid group in the chemical structure,
- wherein the second solid electrolyte membrane is disposed on the first surface of the first solid electrolyte member.
