چکیده انگلیسی
Yttrium-doped strontium titanate (YxSr1−xTiO3), as probable anode material for SOFC, was prepared by solid-state reaction. The solubility of yttrium in SrTiO3 at different temperatures was examined and the electrical conductivities of YxSr1−xTiO3 were measured from 500 to 1000 °C. The effects of doping amount, fabrication atmosphere, and sintering temperature on the electrical conductivity of YxSr1−xTiO3 were investigated. YxSr1−xTiO3 with x=0.08x=0.08 was found to give the maximum electrical conductivity, 71 S/cm at 800 °C in pure hydrogen. Reducing atmospheres and appropriate sintering temperatures play a positive role in improving the electrical conductivity.
