LSM–ScCeSZ nanocomposite was prepared via ultrasonic dispersion of the mixture of perovskite and fluorite powders in acetone in 1:1 ratio with addition of polymethylmethylacrylate. Detailed studies of the real structure and surface properties evolution at sintering under air up to 1100oC revealed pronounced redistribution of elements between the phases without new phases formation. Despite a lower specific conductivity of nanocomposite as compared with LSM, the oxygen mobility estimated by the oxygen isotope exchange and O2 TPD exceeds that of LSM demonstrating a positive role of interfaces as fast oxygen migration paths. Button-cell tests with the LSM–ScCeSZ interlayer between LSNF and a thin YSZ (ScYSZ) layer covering Ni/YSZ cermet demonstrated a high and stable performance promising for the practical application.
