Abstract

The conductivity and ion and proton transfer numbers were measured in La1 − x Sr x Sc1 − y Mg y O3 − α system (x = y = 0.10–0.20). The partial conductivities (total ion, proton, oxygen, hole) and their effective activation energies were calculated. The measurements were carried out in air with respect to humidity (pH2O = 0.04−2.65 kPa) within the temperature range from 630 to 920°C.
