Solid oxide fuel cell （SOFC） is a solid-state device for converting chemical energy into electrical energy, which is widely concerned by researchers due to its green, environmental and high efficiency characteristics. In recent years, the decrease of battery operating temperature has put forward new and higher requirements for SOFC electrolyte, interconnects and eleetrode materials. At present, the electrochemical performance of SOFC in the low temperature working environment is achieved mainly by preparing the electrolyte film, the protective coating of the interconnect and the coating of electrode materials. The electrophoretic deposition （EPD） has the advantages of simple equipment, easy coating, easy operation and so on, which is widely used in the preparation of the materials mentioned above. The research progress of the recent advances in the application of EPD technology in SOFC key components （electrolyte film, alloy interconnect coating, electrode material coating） was reviewed. The development direction in the future was pointed out, which had practical significance for improving battery performance and applications.
