摘　　要：制备了平板式电解质支撑型硫-氧SOFC单电池,组装了单电池发电性能测试系统。对800℃下以不同阳极催化剂制作的单电池开路电压进行测试,LaCrO3作催化剂时获得了最大的开路电压0.406V,确定硫—氧SOFC的最佳阳极催化剂为LaCrO3;考察了单电池开路电压的影响因素;分析了开路电压试验测定值与理论计算值之间存在差距的原因,提出了进一步优化的措施。An electrolyte supported flat-plate single cell for sulfur-oxygen SOFC was manufactured. The open circuit voltage （OCV） of the cells containing potential anode materials were tested at 800 ℃ with an electrochemical property testing system assembled. And the experiments showed that the cell in which LaCrO3 was selected as the anode catalyst had the largest OCV of 0.406 V. It was confirmed that the best anode catalyst for the sulfur-oxygen SOFC was LaCrO3. The main influencing factors for the OCV were analyzed. The causes that there were differences between the theoretical and experimental values were analyzed and the further improving measures were proposed.
