Abstract
This paper presents a thermodynamic investigation on the SOFC-GT combined system for maximizing power generation and optimal energy utilization. The system modeling and analysis are based on the first law of thermodynamics. Performance of the solid oxide fuel cell-based system is analyzed for parametric variation of compression ratio, turbine inlet temperature, fuel utilization factor, and ambient temperature. Direct energy conversion system has an advantage over the indirect system as they reduce the adverse impact on the environment, so solid oxide fuel cell-based systems are environmentally friendly. The maximum.output.of.the considered cycle.is 120.08 kW/Kg of air. The combined efficiency of the system is 51.02% at 1400 K.turbine.inlet temperature. and.13 compression ratio at fixed fuel utilization factor of 80%.
