NOVELTY - Composition comprises 98-99.4 wt.% sulfonated polyetheretherketone, 0.5-1 wt.% sulfonated graphene oxide, and 0.05-1 wt.% amide barium titanate. The degree of sulfonation of the sulfonated Polyether ether ketone (Colorless organic polymer thermoplastic) is 52-70%. The aminated barium titanate is modified barium titanate obtained by modifying raw material barium titanate with a silane coupling agent. The silane coupling agent is at least one of KH-792, KH-550 and KH-602. USE - The composition is useful in composite proton exchange membrane for fuel cell (claimed) ADVANTAGE - The composite proton exchange membrane has high proton conductivity, low methanol permeability, high water absorption rate, strong size stability, good practical value and economic value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the composite proton exchange membrane.
