POLYMER ELECTROLYTE MEMBRANE, METHOD FOR FABRICATING SAME, AND MEMBRANE-ELECTRODE ASSEMBLY COMPRISING SAME

摘要

Provided are a polymer electrode membrane including a porous support including a web of nanofibers of a first hydrocarbon-based ion conductor that are arranged irregularly and discontinuously; and a second hydrocarbon-based ion conductor filling the pores of the porous support, the first hydrocarbon-based ion conductor being a product obtained by eliminating at least a portion of the protective groups (Y) in a precursor of the first hydrocarbon-based ion conductor represented by Formula (1), a method for producing the polymer electrolyte membrane, and a membrane electrode assembly including the polymer electrolyte membrane:
wherein m, p, q, M, M', X and Y respectively have the same meanings as defined in the specification.
