Claim 12:
13. A membrane electrode assembly, comprising:
the composite proton conductive membrane of claim 1;
an anode comprising an anode catalyst on one surface of the composite proton conductive membrane;
an anode gas diffusion layer;
a cathode comprising a cathode catalyst on the other surface of the composite proton conductive membrane; and
a cathode gas diffusion layer;
wherein the composite proton conductive membrane comprises:
an inorganic filler having covalently bonded acidic functional groups and a high surface area of at least 150 m2/g;
a water insoluble ionically conductive polymer and;
a microporous membrane, wherein the inorganic filler is selected from a metal organic framework, a zeolitic imidazolate framework, a covalent organic framework and a combination thereof; and wherein the water insoluble ionically conductive polymer is selected from a group consisting of a polysaccharide polymer, a cross-linked polysaccharide polymer, a metal ion-complexed polysaccharide polymer, an acid-complexed polysaccharide polymer, a cross-linked poly(acrylic acid) polymer, a metal ion-complexed poly(acrylic acid) polymer, an acid-complexed poly(acrylic acid) polymer, a cross-linked poly(methacrylic acid), a metal ion-complexed poly(methacrylic acid), an acid-complexed poly(methacrylic acid), and combinations thereof.
