Total ionic, grain and grain boundary conductivity of traditional 8YSZ and promising 10Sc1CeSZ electrolytes for solid oxide fuel cells (SOFC) were studied. Samples were sintered at 1400°C due to best values of the ionic conductivity, as it was shown earlier. The total conductivity of 10Sc1CeSZ electrolytes at 600°C varied from 0.019 to 0.046 S/cm depending on the initial powder, and for 8YSZ it was 0.059 S/cm. The activation energies were 0.88–1.07 eV and 1.04 eV, respectively. The grain boundary conductivity prevails in YSZ electrolytes due to higher association enthalpy of the grain at temperatures below 560°C which depends on the dopant size. In 10Sc1CeSZ electrolytes the charge transfer passes mainly through the grains: the main contribution to the grain boundary resistivity is given by SiO2 segregations at the grain boundaries in technically pure materials; and grain-to-grain contacts in highly pure materials. The grain boundary resistivity drops twice due to presence of Al2O3 admixtures known for their scavenging effect on SiO2 segregations.
