N2 - BaZr1 - xYxO3 - δ is a proton-conducting oxide that has both high ionic conductivity and good chemical stability, but disadvantageously has low sinterability. In this work, two co-dopant systems, BaZr0.9(Y1 - xMx)0.1O3 - δ (M = Ga, In), were studied with the aim of improving sinterability. In both systems, sinterability was markedly improved. Although the addition of Ga markedly decreased the conductivity of BaZr1 - xYxO3 - δ, the addition of In did not decrease the conductivity significantly. It was shown that BaZr0.9Y0.05In0.05O3 - δ is a practically useful material with a good combination of conductivity and sinterability.
