| Summary: | This paper present a gas turbine cycle combined with a solid oxide fuel cell with hydrogen fuelâs is exergy and energy modeled. In this way all components of the system are separately modeled. Fuel cell model presented, as well as show its behavior in different condition performance. Then, the effects of various parameters on efficiency, exergy was evaluated. And for accuracy, the results were compared with results of references and shows a good match. Increasing the turbine inlet temperature results in decreasing the thermal and exergy efficiency of hybrid system, whereas it improves the net power output. Moreover, an increase in the turbine inlet temperature leads to increases irreversibility and compression ratio leads to decreases irreversibility of the hybrid system. The results in the design point showed that 81% of irreversibility takes place in the fuel cell and combustion chamber(41% in the SOFC and 40% in combustion chamber). Hybrid system efficiency is 58.4%, while the system without SOFC efficiency is 31%, that is a combination of superior performance system. |
