- Ce0.9Gd0.1O1.95 (GCO), is one of the potential candidate electrolytes for intermediate temperature Solid Oxide Fuel Cells (ITSOFC). GCO has high oxide ion conductivity in the intermediate temperature range (500 - 700 degrees C) compared to other C1-yGdyO2-2/y compositions and the Gd3+ ion is the most appropriate dopant material compared to other rare earth materials such as Sm3+, Y3+, Zr3+, etc. Our results show that the fuel cell H-2/Pt/Ce0.9Gd0.1O1.95/O-2 operated in the temperature range 500 - 700 degrees C gives the maximum power densities 0.0049 W/cm(2) at 500 degrees C and 0.0126 W/cm(2) at 650 degrees C for cell voltages 0.6275 V and 0.6278 V, respectively, where the electrolyte was kept in 5% H-2(+ Argon) for 12 hours before use in the fuel cell. Maximum power densities are 0.0038 W/cm(2) at 500 degrees C and 0.0270 W/cm(2) at 650 degrees C for cell voltages 0.5986 and 0.5913 V, respectively, where the electrolyte was kept in 2 % O-2(+ Argon) for 12 hours before use in the fuel cell.
