摘　　要：硫钴化合物具有优良的光学、电学和磁学性能,是近几年的研究热点,本文以(Co,Ni)8S9-MoS_2为阳极催化剂制备的固体氧化物燃料电池在800℃H_2-H_2S中不仅能稳定运行,而且与纯H2相比,当阳极气体中含有25μg/g的H_2S时电池的性能有明显的提升,说明H_2S的存在能提升阳极的电化学活性。The performance and stability of（ Co,Ni）8S9- MoS_2 based anode catalysts in H_2- H_2S SOFC at 800 ℃were investigated,by determining the fuel cell performance. An interesting phenomenon was that the activity of the anode catalysts were higher when the anode fuel was used H_2S- containing H_2. It was clear that the performance using H_2S- H_2- N_2 was much better than using pure H_2,and using H_2- N_2 was the worst.
