Abstract
In this work, we evaluate the physicochemical properties of Sr2-xBaxMMoO6 (M = Mg, Mn, Fe) double perovskites as alternative anode materials for solid oxide fuel cells, for which the effect of substitution of strontium by barium in a full range of compositions is studied. The crystal structure, microstructure, characterization of transport properties (electrical conductivity, Seebeck coefficient) and oxygen content as a function of temperature, as well as chemical stability in oxidizing and reducing conditions are discussed. Fe-and Mo-containing Sr2-xBaxMMoO6 oxides show very high total conductivities with values of 100-1000 S·cm-1, while Sr2-xBaxMMoO6 present good redox stability. © 2016 World Scientific Publishing Company.
