Solid oxide fuel cell (SOFC) has been considered to be one of the most clean and efficient energy conversion devices. However, the market penetration of SOFC still requires continuous materials innovation and fabrication to enhance cell lifespan and reduce cost. At intermediate operating temperatures (500–700 ℃), the polarization loss mainly stems from the oxygen reduction reaction at the cathode. Therefore, it is of great importance to develop new cathodes and new methods with high efficiency and stability. Recently, La_1-xSr_xCo_1-yFe_yO_3-δ (LSCF) has become the wide and practical cathode for intermediate-temperature SOFC, whose physicochemical properties and electrochemical performance have been extensively studied. To further improve its performance and stability, various new electrode fabrication techniques come into view. Surface modification is an effective way to improve the performance and durability of the electrode, which can form a strong interaction between the modification phase and substrate material to have synergistic effect. Research progress in oxide on the surface of LSCF by solution infiltration method will be reviewed. From the point view of modification of binary oxides, ternary oxides and multibasic oxide were discussed, the effects of impregnation on the oxygen ion transport properties, electrochemical performance and long-term stability of substrate materials will be summarized.
