In this paper, performance of agas turbine cycle equipped with a solid oxide fuel cell and Stirling engine is discussed from thermodynamic viewpoint. A thermodynamic analysis is performed for all components of the cycle, and a separate electrochemical and thermal analysis is conducted for the utilized fuel cells.With parametric study of the hybrid system, the influences of compressor pressure ratio, turbine inlet gas temperature, the number of cells, the type of fluid used in the Stirling engine, andthe angular velocity of the Stirling engine on efficiency and power of the hybrid system are investigated.Based on the presented comparison, generated power of the proposed system is about three times larger than the simple gas turbine cycle and 1.3 times larger than the power produced by a hybrid gas turbine and fuel cell system.The obtained results show that the electrical efficiency of the proposed system is about 82 percent, while the fuel cell and gas turbine hybrid system and simple gas turbine cycle efficiencies are about 50 percent and 30 percent, respectively.
