Double doping with Sm and an alkaline earth element (Ca, Sr, Ba) remarkably increases their conductivity in air, mainly because of a decrease in grain boundary resistance [18]. The value of the total conductivity 16. 6 × 10-2 S/cm at 900°C was obtained for Се0. 8 (Sm0. 8Sr0. 2) 0. 2O2-δ in comparison with 12. 1× 10-2 S/cm for Се0. 8Sm0. 2O2-δ. The investigation of the dependence of the total conductivity on oxygen partial pressure showed that double doping with Sr or/and Ba not only lead to an increase in electrical conductivity in air, but also expanded the electrolytic area of ceria-based solid state electrolytes. It gives additional points for their usage under reducing conditions.
