Abstract

Sm_0.5Sr_0.5Zr_1−xNi_xO_3.25−x (x = 0, 0.1, 0.3, 0.5, 0.7) oxides were synthesized via the solid-state reaction method. The structural and morphological properties were studied by X-ray diffraction, a laser size analyzer, and scanning electron microscopy. The Sm_0.5Sr_0.5Zr_1−xNi_xO_3.25−x (x = 0, 0.1, 0.3, 0.5, 0.7) cathodes were symmetrically deposited on a Ce_0,8Sm_0,17La_0.03O_1,9 electrolyte with the spin-coating method, and the area-specific resistance values were determined by electrochemical impedance spectroscopy. Results show that co-doping with the appropriate amount of nickel affects the structural and electrical properties of the cathode compound.

固体氧化物燃料电池用Sm0.5Sr0.5Zr1−xNixO3.25−x材料的合成、表征及电化学性能

摘要采用固相反应法制备了sm0.5 sr0.5 zr1−xNixO3.25−x (x = 0,0.1, 0.3, 0.5, 0.7)氧化物。采用x射线衍射、激光尺寸分析仪和扫描电镜对其结构和形态进行了研究。采用自旋镀膜法将Sm0.5Sr0.5Zr1−xNixO3.25−x (x = 0,0.1, 0.3, 0.5, 0.7)阴极均匀沉积在Ce0,8Sm0, 17la0.030 o1,9电解质上，并利用电化学阻抗谱法测定了阴极的面积比电阻值。结果表明，共掺杂适量的镍对阴极化合物的结构和电学性能都有影响。
