摘要：
The SC2O3-ZrO2 system, which has higher electrical conductivity compared to the Y2O3-ZrO2 system, was examined for electrolyte component of the planar type SOFC. For low temperature operation, the effect of cathode material and Sc2O3 dopant concentration in electrolyte were investigated; maximum power density of 0.6 W/cm(2) was obtained for electrolyte-supported cells using humidified H-2 as fuel and air as oxidant at 800degreesC. Furthermore, the maximum power density of 2.4 W/cm(2) was obtained for anode-supported cells in humidified H-2 as fuel and O-2 as oxidant at 800degreesC.
