A new class of proton-conducting glass ceramic composite membranes was developed for low-temperature fuel tells According to characterizations these membranes demonstrated good mechanical structural thermal and textural properties Moreover they yielded a high proton conductivity of 10(-2) S cm(-1) at room temperature An electrode consisting of a heteropolyacid dispersed in a catalyst layer was also prepared and characterized and the cell performances when using the composite membranes of PWA/PMA doped with eithei ZrO(2) or TiO(2) glass together with the heteropoly acid electrode were extremely high as compared to counterparts with a phosphosilicate glass electrolyte at room temperature The cell evaluation was performed on two ceramic composite membranes i e PWA/PMA-TiO(2)-P(2)O(5)-510(2) (1/1/3/5/90 mol %) and PWA,PMA-ZrO(2)-P(2)O(5)-SiO(2) (1/1/3/5/90 mol %) wit
