The Solid Oxide Fuel Cell (SOFC) promises high plant efficiency, that utilizes a wide variety of fuels, in wide rage application from small to large scale. Mitsubishi Heavy Industries, LTD. (MHI) has been developing SOFC for advanced high-efficiency utility power stations. In this paper, we discuss about the numerical analysis of the SOFC cell stack and the SOFC module, especially on pressurize condition. At first, we present a performance gain of a tubular type SOFC cell stack on pressurized condition, and a numerical study about optimization on the cell configuration is also showed. Finally, the thermal and fluid analysis of the 40kW class sub-module, which is unity module of the 200kW class SOFC module, is showed and verify with the experimental results. And, the 200kW system was constructed in a Japanese national project "Development of the SOFC - Micro Gas turbine (MGT) Combined Cycle System with Tubular Type Cell Stack" by New Energy and Industrial Technology Development Organization (NEDO).
