In this work, W-containing Sr1-xBaxFe0.75W0.25O3-delta (x = 0, 0.5, 1) perovskite-related oxides have been for the first time evaluated in terms of their possible application as anode materials in solid oxide fuel cells. Crystal structure, thermal expansion coefficient, transport properties, oxygen content, chemical compatibility in relation to ceria-based electrolyte, and stability of the materials in reducing atmospheres have been studied. It was found that SrFe0.75W0.25O3-delta and Sr0.5Ba0.5Fe0.75W0.25O3-delta oxides show simple perovskite-type structure with cubic Pm-3m symmetry, while BaFe0.75W0.25O3-delta exhibits hexagonal P6(3)/mmc structure. Small grains (-2 mu m) can be obtained for SrFe0.75W0.25O3-delta compound with very simple, high-temperature synthesis process in air. Large oxygen nonstoichiometry changes of Delta delta approximate to 0.36 were observed for SrFe0.75W0.25O3-delta oxide upon heating in 5 vol.% H-2 in argon. Seebeck coefficient and electrical conductivity measurements revealed that SrFe0.75W0.25O3-delta oxide exhibits p-type conductivity in air and n-type conductivity under reducing conditions. This oxide presents relatively good chemical compatibility in relation to Ce0.8Gd0.2O1.9 electrolyte, and chemical stability in 5 vol.% H-2 in argon up to at least 800 degrees C. Electrochemical impedance spectroscopy studies for SrFe0.75W0.25O3-delta-based cells conducted in pure hydrogen and CH4 indicated the possibility of the application of SrFe0.75W0.25O3-delta as the anode material in SOFCs.
