The LaSrTiCrO (LSTC10) anode material was synthesized by citric acid-nitrate process. The yttria-stabilized zirconia (YSZ) electrolyte-supported cell was fabricated by screen printing method using LSTC10 as anode and (LaSr)MnO (LSM) as cathode. The electrochemical performance of cell was tested by using dry hydrogen as fuel and air as oxidant in the temperature range of 800-900 °C. At 900 °C, the open circuit voltage (OCV) and the maximum power density of cell are 1.08 V and 13.0 mW·cm, respectively. The microstructures of cell after performance testing were investigated by scanning electron microscope (SEM). The results show that the anode and cathode films are porous and closely attached to the YSZ electrolyte. LSTC10 is believed to be a kind of potential solid oxide fuel cell (SOFC) anode material.
采用柠檬酸-硝酸盐法合成了LaSrTiCrO（LSTC10）阳极材料。以LSTC10为阳极、（LaSr）MnO（LSM）为阴极，通过丝网印刷法制备了氧化钇稳定氧化锆（YSZ）电解质支撑电池。在800-900 °C温度范围内，以干燥氢气为燃料、空气为氧化剂对电池的电化学性能进行了测试。在900 °C时，电池的开路电压（OCV）和最大功率密度分别为1.08 V和13.0 mW·cm。通过扫描电子显微镜（SEM）研究了性能测试后电池的微观结构。结果表明，阳极和阴极薄膜呈多孔状且与YSZ电解质紧密附着。LSTC10被认为是一种潜在的固体氧化物燃料电池（SOFC）阳极材料。
