N2 - This work discusses the effect of partial substitution of cobalt in Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) by Mo (VI) cations on the crystal structure, microstructure and transport properties of doped materials. Ba0.5Sr0.5Co0.8−xMoxFe0.2O3−δ (BSCFMx) samples possess specific microstructure consisting of double perovskite domains distributed in the cubic perovskite matrix that results in the suppression of undesirable «cubic–hexagonal» phase transition at x ≥ 0.02. Doped BSCFMx perovskites demonstrate high oxygen permeability, improved CO2 tolerance, enhanced electrical conductivity and chemical compatibility with Ce0.8Gd0.2O2-δ electrolyte that allows to consider them as promising candidates both for oxygen transport membranes and cathodes for intermediate temperature SOFC.
