Inorganic Materials Aims and scope

Abstract—

Pr1 – xSrxFe0.8Co0.2O3 (PSFC) (x = 0.3, 0.4) materials and composites based on them are thought to be promising cathode materials for solid oxide fuel cells. The PSFC powders with micron-sized particles were prepared by self-propagating high-temperature synthesis. Zr0.84Y0.16O2 – δ (YSZ) and Ce0.73Gd0.27O2 – δ (GDC) nanopowders were used as a second component of the composites. It was found that at 1000°C PSFC reacts with the YSZ electrolyte to form SrZrO3, whereas there is no chemical interaction with GDC even at 1200°C. The electrical conductivity of the PSFC with x = 0.4 has been shown to be more than twice that of the material with x = 0.3. Herewith the increase of the Sr concentration in the PSFC leads to an increase of its thermal expansion coefficient (TEC), which exceeds that of GDC. The formation of PSFC/GDC composites makes it possible to achieve a better match in thermal expansion and sintering kinetics between the cathode and electrolyte materials. However, the electrical conductivity of the studied composites is a factor of 2–5 lower than that of the initial PSFC materials.
