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.}, pages = {A105--A109}, title = {A Proton-Conducting In^3+ -Doped SnP2O7 Electrolyte for Intermediate-Temperature Fuel Cells}, volume = {9}, year = {2006} }
