High-efficiency Clean Power Generation System Based on Solid Oxide Fuel Cell

Introduction Solid oxide fuel cell (SOFC) is a high-tech product that can convert chemical energy in hydrocarbon fuel into electrical and heat through electrochemical reaction. The advantages of fuel flexibility, high efficiency, high quality heat, silent operation, low emission and modular installation make SOFC one of the effective ways to achieve efficient and clean utilization of fossil energy. Method  The article explained the principle of SOFC power generation, introduced the domestic and foreign SOFC technology and industrialization status, and analyzed the application scenarios of SOFC-based distributed combined heat and power, combined cycle power generation, and new generation integrated gasification fuel cell cycle (IGFC) power generation system. Result  Through the SOFC power generation technology route and industrialization research, the existing problems are analyzed, considering China's resource endowment and demand for efficient and clean power generation devices, the future development trends in this field are prospected. Conclusion  Compared with the domestic and foreign SOFC technology gap, based on the domestic advantage in the core materials of SOFC stacks, the SOFC system integration technology should be strengthened to lay a foundation for the new generation of clean and efficient power generation industry centered on SOFC.
