摘要:本文通过EDTA-柠檬酸络合法制备了一系列用于固体氧化物燃料电池阴极材料的Ce掺杂的SmxSr1-xCo1-yCeyO3-d(x= 0.3, 0.5; y=0.05, 0.1)氧化物。对其晶体结构,微观形貌,热膨胀及电化学性质等进行了系统性的研究。研究发现,Sm0.3Sr0.7Co0.95Ce0.05O3-d(SSCC37-9505)具有单一的钙钛矿相,而其他样品(x=0.3, 0.5)则是同时具有钙钛矿相和CeO2相的两相组成(SmxSr1-xCo1-yCey-zO3-d·zCeO2 (0 For information in English, please click here A novel perovskite-type cerium doped SmxSr1-xCoO3-d oxides as potential cathode materials for solid oxide fuel cells Abstract:A series of new oxides with the nominal composition of SmxSr1-xCo1-yCeyO3-d (x=0.3, 0.5; y=0.05, 0.1) were synthesized. Their crystal structure, morphology, thermal expansion and electrochemical properties were systematically investigated. A phase-pure perovskite-type Sm0.3Sr0.7Co0.95Ce0.05O3-d oxide is obtained, while the other samples are actually composed of B-site cation deficient SmxSr1-xCo1-yCey-zO3-d (0 Keywords:
