Thermal, electrical and electrocatalytical properties of LaxSr1-xTiO3, where x = 0.1, 0.2, 0.3, 0.35, and 0.4, perovskite compositions are studied in relation to their potential use as solid oxide fuel cell (SOFC) anode materials. An emphasis is made on the effect of oxidation-reduction cycling on these properties. Depending on the dopant amount, x, and the oxygen partial pressure, LaxSr1-xTiO3 possesses an electrical conductivity on the order of 0.01-500 S/cm at 800-1000 degreesC. The thermal expansion of LaxSr1-xTiO3 is close to that of yttria-stabilized zirconia (YSZ). No significant chemical expansion or contraction of LaxSr1-xTiO3 with x < 0.4 is observed when exposed to a wide variation in pO(2). LaxSr1-xTiO3 is found to be dimensionally and chemically stable when subjected to oxidation-reduction cycling. Cell tests demonstrated the potential ability of the doped titanates to be used as SOFC anodes.
