Abstract
The conductivity of single-phase ceramic materials based on proton-conducting perovskite La0.9Sr0.1ScO3–α containing from 0.3 to 47 at % Fe in the scandium sublattice has been studied. Synthesis has been performed by burning with ethylene glycol. Measurements have been carried out by the four-probe (500–900°C) and impedance (100–500°C) methods in oxidizing and reducing atmospheres, as well as at different pressures \({p_{{O_2}}}\) (2.1 × 104–10‒15 Pa) and \({p_{{H_2}O}}\) (0.04–2.5 kPa). Substitution of scandium with iron significantly decreases the proton conductivity.
