Molten carbonate fuel cells have been revealed to be very attractive power generation system, promising highly efficient electricity generation and very low environmental impact. The integration of micro gas turbine and molten carbonate fuel cells has been proposed in the last years as an extremely efficient solution for power generation. A steady-state thermodynamic exergetic model for MCFC/MGT hybrid power system is developed on the IPSEpro simulation platform, and applied to a performance analysis of exergy. The exergy method highlights irreversibility within the system components, and it is of particular interest in this paper. The simulation results show that the coupling of MGT with a MCFC reactor has shown a potential for an exergy efficiency of plant over 55% at design point and high efficiency at off-design point compared to other conventional power system.
