Development of 25kW Class SOFC Module

Mitsubishi Heavy Industries, Ltd. (MHI) and Electric Power Development Co.,Ltd. (JPOWER) started SOFC module development in collaboration in 1991. Since 2001 we have focused on improvement on SOFC module aiming for high reliability and lower cost. The 5kW-class Cartridge test with 104 cell-tubes was successfully accomplished in 2003. We also executed a dynamic simulation and thermal fluid analysis of improved SOFC module and control system development under atmospheric pressure. In 2006, we have succeeded in the operation of 25kW-class sub- module that will be a unit of highly scalable SOFC system. This module dose not need heating support to maintain the operating temperature, because the fuel exhaust gas from the SOFC module is burned in the combustor and used for heating supply air to SOFC module.
