The proton transport properties of La_0.9M_0.1YbO _3-δ (M = Ba, Sr, Ca, Mg) were studied by the electrical conductivity measurement technique in the temperature range of 673-1173 K. The proton concentration was estimated by the weight changes due to the hydration reaction. The electrical conductivity and proton concentration of La _0.9Ba_0.1YbO_3-δ were the highest in La_0.9M_0.1YbO_3-δ. The electromotive force of a hydrogen gas concentration cell using La_0.9Ba _0.1YbO_3-δ as the electrolyte was observed at 673-1073 K, and was in a good agreement with the theoretical values assuming that the proton transport number was unity.
