Abstract
为了解决固体氧化物燃料电池(SOFC)陶瓷连接材料的低成本制备难题, 设计了与LaCrO3基连接材料和Ni基阳极均具有良好烧结匹配性能的新型复合材料NiO/ La0.7Ca0.3Cr0.97O3−δ (LCC97)作为管式SOFC的支撑体. 详细研究了NiO含量(5wt%、25wt%、50wt%、75wt%)对复合支撑体的烧结性能、微观组织、孔隙率、电导性能、热膨胀系数等的影响, 结果表明: LCC97与NiO具有优良的烧结和化学匹配性能, NiO/LCC97(1:1, wt%)具有最优的综合性能. 以其为支撑体, 采用浆料浸渍法制备LCC97湿膜, 1400℃空气条件下共烧, 获得了致密LCC97连接材料薄膜.
