“…MHI tested controllability of the MGT with a dummy module, which simulated the volume of the SOFC module. At the steady operation and the transient state, which was the start of the air blower, the fuel switching from city gas to low-calorie gas, and the load dumping, it was confirmed that MGT could operate within the allowance limit of the differential pressure in SOFC (3). In June 2006, MHI succeeded in verification test of a 40 kW class pressurized SOFC module and MGT combined cycle system for the first time in Japan.…”

SOFC-gas turbine combined cycle system is able to attain extremely high efficiency over 70% (LHV). Mitsubishi Heavy Industries (MHI) has been developing SOFCs since 1984. Now, MHI is integrating SOFC with a gas turbine for a combined cycle power generation system. MHI has improved the components and the control technology for the combined cycle system; this includes improvement of the cell stack, verification of pressurized operation and control of SOFC module, and the combustor for low-calorie fuel. In 2006, MHI operated a combined cycle system with a maximum power output of 75 kW, for the first time in Japan. Now, MHI is ready to manufacture a 200 kW class SOFC-MGT combined cycle system, which will be operated in 2007.

“…From equations [2] and [3], the concentration polarization depends on the thickness of gas the diffusion layer thicknessδ[m] and effective diffusion coefficient D eff [m 2 /s], porosityε, tortuosityτand main gas concentration C b [mol/m 3 ] Activation Polarization η A. The activation polarization is considered with the Butler-Volmer equation indicated in [4] and its development [5). The exchange current density i 0 was measured by the actual cell performance.…”

Mitsubishi Heavy Industries (MHI) has been developing tubular type SOFC since 1984. With the support of NEDO during the fiscal years 2003 to 2004, some materials have been investigated in order to reduce resistance. The cell tube which is applied advanced materials had been developed, and was operated at 900{degree sign}C, 0.4MPa, 300 mA/cm2. Its output density of 0.21W/cm2 was achieved. The consignment research of NEDO is continued from 2005 to 2007. In this project, we are now developing a simulation technology of performance in order to optimize the cell tube configuration and advanced materials for a high power density cell tube. In 2006, a cell tube that was optimized by advanced simulation technology was developed. The cell tube was operated at 900°C, 0.6MPa, 750mA/cm2. Its output density of 0.5W/cm2 was achieved. This paper reports the current status of improvement of high power density tubular type SOFC at MHI.
