System analysis of Solid Oxide Fuel Cell (SOFC)/Gas Turbine (GT) combined cycle power generation systems were carried out by means of numerical simulation method. In the first report, the influence of the SOFC operation conditions on the efficiencies of the system was discussed. This report studied the influence of the system configuration on the system performance. First, the system performance using internal reforming was compared with that using external reforming. Next, the system performance using cathode gas recycling or anode gas recycling was studied. As a result, it was clarified that the use of the internal reforming or gas recycling was effective to raise the gas turbine inlet temperature, but did not always make the system efficiency improvements. However, when the Heat Recovery Steam Generator is installed in the system using anode gas recycling, the efficiency of the SOFC/GT/Steam Turbine combined cycle power generation system was estimated to be over 65%.
