CeO2基固体氧化物燃料电池连接体薄膜的双层共烧制备研究
Journal of Synthetic Crystals(2014)
Abstract
为了改善CeO2基SOFC阳极与LaCrO3基连接材料的共烧匹配性能,本研究将少量CeO2粉体添加到La0.7Ca0.3CrO3-δ连接材料中作为烧结助剂.相关性能测试表明CeO2的引入可以显著提高La0.7Ca0.3 CrO3-δ在空气条件下的烧结和电导性能,完全可以满足中温SOFC连接材料的性能要求.以NiO/SDC(质量比6∶4)为阳极支撑体,采用浆料浸渍涂膜工艺制备La0.7Ca0.3CrO3-δ +2% CeO2(质量比)连接体湿膜,1400℃空气条件下双层共烧,成功获得致密连接体薄膜.
