Abstract

Subsolidus equilibria in air in the La2O3–Ga2O3–CeO2 system were studied with the aim of obtaining information on possible interactions between a LaGaO3-based solid electrolyte and CeO2 during preparation of the anode in solid oxide fuel cells. No ternary compound was found. The tie lines are between La4Ga2O9 and the end of the CeO2 solid solution range with composition La0.5Ce0.5O1.75 and between the LaGaO3 and CeO2 range of solid solutions.
