【摘要】 通过共沉淀法制备出Lal-xCaxCr03(x=0,0.1,0.2,0.3)作为阳极催化剂,分别以钇稳定氧化锆(YSZ)粉体和La0.6Sr0.4C00.2Fe0.803-x(LSCF)粉体作为硫-氧燃料电池(SOFC)电解质材料和阴极材料。发现在700～800℃时,Lal xCaxCr03(x=0,0.1,0.2,0.3)对硫-氧SOFC这一新型SOFC具有明显的催化效果,当选择La0.8Ca0.2Cr03为阳极催化剂时,测得800℃时单电池开路电压为560mV,达到理论计算值的75%。其余催化效果为:La0.9Ca0.1Cr03>LaCr03>La0.7CaO.3Cr03。
【Abstract】 La1-xCaxCr03(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 indicated that in the range of 700～800℃,La1-xCaxCr03(x=0,0.1,0.2,0.3) have clear catalysis effect for sulfur-oxygen SOFC.When La0.8Ca0.2CrO3 was selected as anode catalyst,at 800℃,the OCV is 0.560 V,which reaches the 75%of the theoretical OCV value.Furthermore,the rest of the catalytic effect was: La0.9Ca0.1CrO3>LaCr03>La0.7Ca0.3CrO3.
