Abstract

Present work considers the thermo-economic analysis of solid oxide fuel cell (SOFC), gas turbine (GT) and steam turbine (ST) hybrid system. The annualized cost is considered to economic analysis and for thermodynamics analysis, the energy equations are solved to obtain the energy efficiency. Directly or indirectly connection of SOFC and GT and also heating the SOFC input reactants with only GT output or the GT output with the after burner output offers four different configurations. These different configurations can cause condition that SOFC and GT have different operating pressure or the same ones, and also can cause different SOFC operating temperatures. Results show that the hybrid system with SOFC and GT direct connection and using only the GT output for heating is the optimum thermodynamics hybrid system with 59. 3% efficiency and 416290 $/year annualized cost for 1000 A/m2 current density. And the hybrid system with these condition is the optimum economic hybrid system with 52. 7% efficiency and 212438 $/year annualized cost for 5000 A/m2 current density.
