| Summary: | Novel cathode materials for solid oxide fuel cells based on Ba-doped Sr2Fe1.5Mo0.5O6 (Sr2-xBaxFe1.5Mo0.5O6-δ where x = 0.3, 0.5, 0.7 and 0.9) were synthesized by solution combustion method and sintered at 1200°C. Their phase composition, microstructure and electrical conductivity were studied. It was shown that the maximal electrical conductivity of 18.5 S/cm at 450°C was measured for the Sr1.3Ba0.7Fe1.5Mo0.5O6-δ ceramics. The superior chemical compatibility between the Sr2-xBaxFe1.5Mo0.5O6-δ cathode and Gd0.2Ce0.8O1.9 electrolyte was confirmed, as well as good matching between thermal expansion coefficients of the cathode and electrolyte materials. |
