A computational model of a hybrid pressurized solid oxide fuel cell (PSOFC) generator/gas turbine power plant is developed using classical thermodynamic analysis in conjunction with electromechanical, fluid-mechanical, and heat transfer simulations in the fuel cell by a commercial software. The thermodynamic analysis is based on energy and exergy balances. A case study is reported in which the plant contains a Siemens–Westinghouse PSOFC generator and a Solar Turbines Mercury-50 gas turbine. Among the calculated quantities for a range of fuel cell current are the plant output power, first-law efficiency, and exergetic efficiency.
