Intrinsic Creep Resistance of Two Solid Oxygen Fuel Cell Electrolytes: Cubic Zirconia Versus Doped Lanthanum Gallate.

Abstract

Knowledge of the creep parameters for cubic zirconia and doped lanthanum gallate allowed for a determination of the intrinsic creep resistance of each material in the temperature range from 800 to 1000 deg C, where they are to be utilized as electrolytes in solid oxygen fuel cells. The results revealed that the intrinsic creep resistance of cubic zirconia is much higher than that of doped lanthanum gallate. This is most likely a result of their different crystal structures.
