In order to analyze the performance of the system under different cycle modes, use Matlab /Simulink software analyzes the effects of different fuel flow rates on the power and efficiency of the new SOFC-MGT bottom cycle system, and compares the output power of the new SOFC-MGT bottom cycle system with the traditional SOFC-MGT bottom cycle system and top cycle system A comparative analysis was carried out. The research results showed that the maximum output power of the system was 1.33kW, 1.29kW and 1.48kW, and the output efficiency was 50.6%, 56.3%, and 65.6%, respectively, under the three circulation modes. In terms of output power, the output performance of the SOFC-MGT top cycle system is better than that of the two bottom cycles, and the output performance of the new SOFC-MGT bottom cycle system is better than that of the traditional bottom cycle. In terms of turbine exhaust energy recovery.The new SOFC-MGT bottom circulation system is superior to the top circulation and the traditional bottom circulation system.
