Abstract
A new PEM and fuel cell using that PEM are disclosed. The proton electrolyte membrane (PEM) comprises a polymer matrix and an ionically conductive ceramic material adapted to create a superconductive interface, the ceramic material being uniformly dispersed throughout the matrix. The polymer matrix is selected from the group consisting of proton exchange polymers, non-proton exchange polymers, and combinations thereof. The material is selected from the group consisting of beta alumina oxides, SnO2(nH2O) , fumed silica, SiO2, fumed Al2O3, H4SiW12O2(28H2O), tin mordenite/SnO2 composite, zirconium phosphate-phosphate/silica composite.
