A strategy to regulate the functional properties of the MIEC oxides by doping them with ferro-active highly-charge cations B5 + (Nb, Ta) and B6 + (Mo, W) based on the concepts of the MIEC oxides as ferroelastics. Development of nanostructured membrane and electrode materials that demonstrate stable performance in long-term tests under conditions appropriate to the operating conditions of solid oxide fuel cells (SOFC) and catalytic membrane reactors.
Development of a novel method for construction of detailed equilibrium "3-δ-pO2-T" diagrams for MIEC oxides based on the determination of oxygen non-stoichiometry as a continuous function of the oxygen partial pressure.
The development of a novel relaxation method for the study of oxygen exchange in MIEC oxides, in which the accurately measured parameter is pO2.
A new "isostochiometric" approach for analyzing the kinetic data on the oxygen exchange of nonstoichiometric MIEC oxides with a gas phase.
