摘要

The present invention provides: a proton-conducting polymer/synthetic resin composite which comprises a polymer electrolyte that exhibits proton conductivity and includes a fluoropolymer, a hydrocarbon-based polymer, etc. and that has further improved mechanical properties; and a proton-conducting electrolyte membrane produced from the composite. The fluoropolymer may be a perfluorosulfonic acid polymer. The hydrocarbon-based polymer may be a sulfonated polyphenylsulfone or another sulfonated polymer having a specific structure. The proton-conducting polymer is the hydrocarbon-based polymer, and the hydrocarbon-based polymer and the synthetic resin may have been at least partly crosslinked with each other. The synthetic resin may be a heat-crosslinking type functional synthetic resin. The synthetic resin may be at least one resin selected from the group consisting of Vinylon, polyimides, phenol-formaldehyde resins, melamine-formaldehyde resins, urea resins, nylons, and polyurethanes.
