摘要：

The La0.8Sr0.04Ca0.16Co0.6Fe0.4O3-delta(LSCCoF) and La0.9Sr0.1Ga0.8Mg0.2O3 (LSGM) powders were synthesized by glycine-nitrate combustion process and conventional solid-state reaction method, respectively. The LSCCoF-LSGM composite cathode material was successfully elaborated and deposited on dense pellets of the LSGM electrolyte by means of slurry spin-coating process. The cathode films with the best surface morphology and microstructure were obtained when the operating parameters fixed as follows: the content of ethyl cellulose which acted as pore former and binder is 10 wt.%, the content of terpineol which acted as modifier is 5 wt.%, the speed of rotation rate is 3200 r/min and the best post-deposition sintering temperature is 1000 degrees C.
