Abstract: The composite oxide with perovskite-like structure developed in these years could be a promising cathode of IT-SOFC. In this paper, the research progress of A_2BO_4-type and AA' B_2O_5-type perovskite-like cathode materials was reviewed, and summarized the property of the two types of materials as IT-SOFC cathodes. Improving the microstructure and enhancing the electrochemical performance and thermal stability for perovskite-like cathode will be the emphases for future's research.
