<P>PROBLEM TO BE SOLVED: To provide a proton exchange membrane (PEM) in which a moving speed of a proton traversing the PEM is improved so as to exceed a moving speed of methanol traversing the PEM. <P>SOLUTION: An electrolyte comprises a polymer matrix and an ionically conductive ceramic material adapted to create a superconductive interface in a fuel cell having an anode, a cathode and the electrolyte disposed between the anode and the cathode. The ceramic material is uniformly dispersed throughout the matrix. In the fuel cell furthermore, the polymer matrix is selected from a group composed of proton exchange polymers, non-proton exchange polymers, and combinations thereof. The ceramic material is selected from a group composed of beta alumina oxides, SnO<SB>2</SB>(nH<SB>2</SB>O), fumed silica, SiO<SB>2</SB>, fumed Al<SB>2</SB>O<SB>3</SB>, H<SB>4</SB>SiW<SB>12</SB>O<SB>2</SB>(28H<SB>2</SB>O), a tin mordenite/SnO<SB>2</SB>composite, and a zirconium phosphate-phosphate/silica composite. The PEM contains the ionically conductive ceramic material adapted to create the superconductive interface dispersed into the polymer matrix and is used for the fuel cell. <P>COPYRIGHT: (C)2004,JPO |
