ABSTRACT:
Disclosed herein is solid polymer electrolyte composition comprising solid polymer electrolyte and at least one metal catalyst selected from the group consisting of platinum, gold, palladium, rhodium, iridium and ruthenium contained in the said solid polymer electrolyte. The said composition may further contain a metal oxide. The membrane made of the composition possesses the abilities of producing water by itself and of retaining the water so that the ionic conductivity and the effect of depressing the crossover is excellent. Accordingly, the cell employing the membrane possesses superior cell performance.
