Proton Conducting Membranes for High Temperature Fuel Cells with Solid State “water Free” Membranes

ثبت نشده
چکیده

A “water free,” proton conducting membrane for use in a fuel cell is fabricated as a highly conducting sheet of converted solid state organic amine salt, such as converted acid salt of triethylenediamine with two quaternized tertiary nitrogen atoms, combined with a nanoparticulate oxide and a stable binder combined with the converted solid state organic amine salt to form a polymeric electrolyte membrane. In one embodiment the membrane is derived from triethylenediamine sulfate, hydrogen phosphate or trifiate, an oxoanion with at least one ionizable hydrogen, organic tertiary amine bisulfate, polymeric quatemized amine bisulfate or phosphate, or polymeric organic compounds with quatemizable nitrogen combined with Nafion to form an intimate network with ionic interactions.
