The planar solid oxide fuel cell (SOFC) with the Y2O3 stabilized ZrO2 electrolyte is expected to be a candidate for the distributed power sources in the next generation due to its high efficiency of power generation. In this study, we have analyzed the system performance of the SOFC and gas turbine combined cycle of about 500 kW power output, using a two-dimensional simulation program for planar SOFC with the internal reforming. The effects of cell temperature, SOFC pressure, recirculation ratios of fuel and air, utilization ratios of fuel and air, and average current density at SOFC on the system efficiency were analyzed under typical operating condition taking account of realistic efficiencies and heat losses.
