✦ Synopsis

This study deals with the thermodynamic analysis of molten carbonate fuel cell combined with a gas turbine, based on the first-and second-law of thermodynamics. The mass, energy, entropy and exergy balance equations are written and applied to the system and its components. Some parametric studies are performed to investigate the change of system performance through energy and exergy efficiencies with the change of operating conditions. The irreversibilities occuring in different devices of the integrated system are also investigated through the exergy destruction analysis in these devices. The maximum output work of the MCFC is estimated to be 314.3 kW for an operating temperature of 650 C. The overall energy and exergy efficiencies achieved for this system are 42.89% and 37.75%, respectively.
