We report proton conduction in In^3+ -doped SnP2O7 in the temperature range from 100 to 300℃, and the performance of a H2 -air fuel cell using this material as the electrolyte. The proton conductivity of In^3+ -doped SnP2O7 was more than 10^-1 S cm^-1 between 125 and 300℃, and a conductivity value of 1.95×10^-1 S cm^-1 was achieved at 250℃. The resulting fuel cell exhibited a reasonable power density of 264mWcm^-2 at 250℃ (electrolyte thickness=0.35mm), together with perfect tolerance toward 10% CO and good thermal stability in unhumidified conditions.
