Abstract:
1. A proton selective membrane for functioning as an electrolyte in a solid polymer electrolyte fuel cell that is produced by providing one or more proton conducting template molecules selected from the group consisting of phosphoric acid, phosphonic acid, and phosphinic acid, providing one or more functional monomers selected from the group consisting of 4-vinylpyridine, acrylic acid, and acrylamide to interact with the proton conducting template molecules, and providing at least one cross-linking agent to covalently bond polymer chains created with the proton conducting template molecules and the functional monomers by polymerization to create an imprinted polymer which possesses ionic conductivities that are independent of water thereby enabling its use at high temperatures and which employs protonic channels to transfer protons through the imprinted polymer.
