| Abstract: | La1-xCaxCrO3 (x=0,0.1,0.2,0.3) were prepared by co-precipitation method and acted as anode catalysts of sulfur-oxygen SOFC with YSZ as electrolyte material and LSCF as cathode material.The open circuit voltage of cells was tested.The results of the OBV test indicate that in the range of 700-800 ℃,La1-xCaxCrO3 (x=0,0.1,0.2,0.3) has clear catalysis effect on sulfur-oxygen SOFC.When La0.8Ca0.2CrO3 was selected as anode catalyst,at 800 ℃,theOCV is 0.560V,whichreaches 75%ofthetheoretical OCV value.Furthermore,therestofthecatalytic effect is:La0.9Ca0.1CrO3> LaCrO3>La0.7Ca0.3CrO3. |
