制备钴镍黄铁矿作为固体氧化物燃料电池的耐硫阳极

摘要

The performance and stability of (Co, Ni) 8 S9-MoS2 based anode catalysts in H2 -H2 S 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 H2 S-containing H2.It was clear that the performance using H2 S-H2-N2 was much better than using pure H2 , and using H2 -N2 was the worst.%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）8 S9－MoS2为阳极催化剂制备的固体氧化物燃料电池在800℃ H2－H2 S 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 H2 S 时电池的性能有明显的提升，说明 H2 S 的存在能提升阳极的电化学活性。
