Detailed analysis of exergy on the integrated gasification combined cycle (IGCC) incorporated with a solid oxide fuel cell (SOFC) was conducted to explore the performance characteristics of the system. The exergy destruction and exergy efficiency were analyzed at different syngas mixture compositions by varying the compressor pressure ratio. SOFC-gas turbine system included gasifier, gas cooler, SOFC, compressor and gas turbine, combustion chamber and heat recovery system generator. Results showed that using hydrogen-enriched syngas mixture increased the net power and the exergy efficiency. The highest exergy destruction occurred at the gasifier, and combustion chamber.
