Abstract: For the high-temperature solid oxide fuel cell/gas turbine (SOFC-GT) hybrid system technology, the research progress and challengers of the demonstration project, hardware-in-the-loop simulation and computational simulation of the SOFC-GT hybrid system were discussed. The future development trends of "high efficiency and cleanliness, combined cycle, and micro-distributed power generation" of this technology were discussed, as well as the corresponding extended technologies such as combustion chamber and turbine design.
