Abstract

Novel cathode materials for solid oxide fuel cells based on Ba-doped Sr2Fe1.5Mo0.5O6 (Sr2-xBaxFe1.5Mo0.5O6-? 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-? ceramics. The superior chemical compatibility between the Sr2-xBaxFe1.5Mo0.5O6-? cathode and Gd0.2Ce0.8O1.9 electrolyte was confirmed, as well as good matching between thermal expansion coefficients of the cathode and electrolyte materials.
