A simulation model of the solid oxide fuel cell-gas turbine (SOFC-GT) hybrid system on the basis of the aviation kerosene reforming was established. The effect of two heat recovery methods on the reformers and the effect of the turbine positions on the system efficiency were studied to obtain the optimal system architecture. The performance of the SOFC-GT hybrid system was evaluated by studying the effects of the compressor pressure ratio

fuel utilization ratio

fuel flow rate and air flow rate. Results showed that the efficiency of the best hybrid system can reach 45% at the design condition

and the system demonstrated excellent performance. The efficiency and power of the system reached the peak with the fuel utilization ratio equaling to 082. Moreover

the efficiency and power could be improved with the growing fuel flow rate (from 0051 1 mol/s to 0058 4 mol/s)

while the increasing compressor pressure ratio (from 25 to 33) or air flow rate (from 37 mol/s to 44 mol/s) could result in the reduction of the efficiency and power.
