Abstract: La0.8Sr0.2MnO3-σ coated Ba0.5Sr0.5Co0.8Fe0.2O3-σ (LSM-BSCF) composite powders was successfully synthesized by solid-solution method. Some property of material was investigated, such as the phase composition, morphology, ability of ant-CO2 gas poisoning, and electrochemical performance. The result showed the material have good crystal structure, well ability of ant-CO2 gas poisoning, and the electrochemical performance is reduced.

Key words: solid oxide fuel cells; LSM-BSCF; ant-CO2 poisoning
