Abstract

The electrode properties of Ba0.5Sr0.5CoyFe1-yO3-δ {BSCF(5/5/10y/10(1-y))} on a Ce0.8Sm0.2O1.9 electrolyte were investigated. BSCF powders were synthesized by a solid-state reaction. The electronic conductivities of BSCFs increased with increasing Co content and BSCF(5/5/8/2) showed the highest conductivity of 38 S cm-1 at 600oC. The electrode resistance was measured on symmetric cells, BSCF/Ce0.8Sm0.2O1.9/BSCF, over the temperature range from 600oC to 800oC. The electrode resistances decreased with increasing Co content and BSCF(5/5/8/2) showed the lowest electrode resistance in the whole temperature range, having an electrode resistance of 0.62 cm2 at 600oC.
