A modified DC Hebb–Wagner polarization method for determining the partial protonic electrical conductivity in mixed-conducting BaGd_0.3La_0.7Co₂O_{6−<i>δ</i>}

Abstract

The modified DC Hebb–Wagner polarization method with an electron and oxygen-ion blocking electrode was for the first time applied to study partial protonic conductivity in triple-conducting oxides: BaZr 0.7 Ce 0.2 Y 0.1 O 3− δ and BaGd 0.3 La 0.7 Co 2 O 6− δ .
