%X a novel anode material for intermediate temperature solid oxide fuel cells with a composite of laxsr1-xtio3 has been synthesized by a sol-gel auto-combustion method. x-ray diffraction (xrd) shows that laxsr1-xtio3 has good chemical compatibility with gd0.2 ce0.8o1.9 electrolyte. the thermal expansion coefficient (tec) of the as-prepared anode material is similar to that of gd0.2 ce0.8o1.9. the electric conductivity measurements show that the conductivity of laxsr1-xtio3 increases with the increasing of lanthanum contents and reached a maximal value at x=0.3. at 800oc, the electrical conductivity of la0.3sr0.7tio3 is 184scm-1.
