Microstructure and electrochemical behavior of Sm0.5Sr0.5CoO3deposited by solution precursor plasma spraying

摘要：

　　Solution precursor plasma spraying (SPPS) was employed to prepare porous Sm0.5Sr0.5CoO3 (SSC) cathode for solid oxide fuel cell (SOFC).The surface and cross-sectional morphology of the SSC deposit were characterized by scanning electron microscopy.The effect of annealing on SSPS SSC microstructure was examined.The electrochemical behavior was investigated through the impedance spectroscopy.The results showed that the SPPS SSC cathode exhibits multidimensional porous microstmcture.The electrochemical measurement result showed that the specific surface resistance of SSC decreased significantly with the increase of test temperature and yielded a specific surface resistance of 2.6 Ω·cm2 at 800℃.
