ABSTRACT
Mitsubishi Heavy Industries, Ltd. (MHI) have been developing Solid Oxide Fuel Cell (SOFC), which has high efficiency and the possibility of fuel diversification.
We have been developing three types of SOFC, namely Tubular, MOLB (Mono-block Layer Built) and planar type. The research on a tubular type SOFC was started in 1984 using the plasma spray technology. In 1990, a 1kW module was tested and the maximum power output of 1.3kW was recorded. This module was subsequently moved to a power station for a field test. A continuous operating test of 1,000 hours had been performed until November 1991. MHI has also been developing MOLB and Planar type SOFC with sintering method. A 1kW module test of MOLB type is scheduled in 1992. For Planar type, 10 cells stack of 130mm diameter has been successfully tested and the output of 115W was recorded.
This paper reviews MHI’s R & D activities and results for the three types of SOFCs.
