Abstract :
This article presents a steady-state thermodynamic model of a solid oxide fuel cell/gas turbine hybrid cycle which developed by using a simulation software, MATLAB®. The hybrid model integrates a zero-dimensional level SOFC model with gas turbine. The hybrid system was used to study the effects of some operation parameter such as SOFC operating temperature, and current density on the specific work output, electrical efficiency, and exergy efficiency of a generic hybrid cycle. The results show that if the SOFC operating temperature, the power output, electrical efficiency, and exergy efficiency increase. The electrical efficiency of the hybrid system increase from 62% to 68%, and the exergy efficiency of the hybrid system increases from 60% to 66% when the operation temperature increases from 600°C to 750°C at a current density of 6000 A/cm2. On the other hand, the system efficiency and exergy decreases with an increase in the current density.
