Direct carbon solid oxide fuel cell （DC-SOFC）is an energy conversion device with high output efficiency, simple structure and high fuel utilization. Although the development of direct carbon solid oxide fuel cells has a long history, the research depth is low. In this paper, the working principle, thermal effect and structure type of direct carbon solid oxide fuel cell were systematically introduced. The research progress of carbon fuel and anode materials of direct carbon solid oxide fuel cell at home and abroad was reviewed. The advantages and disadvantages of the battery and the related literature patents were analyzed. The future development trend of DC-SOFC was prospected.
