Proton-conducting electrolyte membrane, method for producing proton-conducting electrolyte membrane, and polymer electrolyte fuel cell

摘要

A proton conductive electrolyte membrane having a pore-containing inorganic porous membrane filled with a proton conductive polymer, wherein the proton conductive polymer is a haloalkylated and sulfonated polymer compound and the following general formula: A proton conductive electrolyte membrane which is a reaction product with the compound represented by (1). It is possible to provide a proton conductive electrolyte membrane having a sufficiently high proton conductivity and a sufficiently low methanol permeability, a method for producing the same, and a polymer electrolyte fuel cell using the proton conductive electrolyte membrane. Wherein R 1 represents an alkyl group having 4 or less carbon atoms, R 2 represents an arbitrary organic group, and m and n are all integers of 1 to 3, provided that m + n = 4 , When m is 2 or 3, R2 may be a different organic group.)
