Title:
PROTON CONDUCTING MEMBRANES FOR HIGH TEMPERATURE FUEL CELLS DEVELOPED WITH SOLD STATE "WATER FREE" PROTON CONDUCTING MEMBRANES
Document Type and Number:
WIPO Patent Application WO2003063266
Kind Code:
A3
Abstract:
A "water free," proton conducting membrane (10) 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 quaternized amine bisulfate or phosphate, or polymeric organic compounds with quaternizable nitrogen combined with Nafion to form an intimate network with ionic interactions.
