The Solid Oxide Fuel Cell-Inverted Brayton Cycle (SOFC-IBC) hybrid power generation system offers a solution to the challenge of directly coupling atmospheric pressure SOFC with the traditional Brayton cycle due to pressure mismatches. This study employs process simulation and theoretical analysis to establish a model of the atmospheric pressure SOFC-Double IBC hybrid power generation system based on CO2 recycling, investigating the impact of fuel utilization on system performance and further exploring its internal energy conversion processes through exergy analysis. The results indicate that when the fuel utilization factor is 0.85, the system achieves a peak total efficiency of 76.74%, with an output power of 182.77 kW and an exergy efficiency of 63.46%.
