MOLB (Mono block Layer Built) type SOFC has many advantages such as high density of electric power generation, small space requirement and suitableness for mass production, etc. Chubu Electric Power Company, Inc. (CEPCO) and Mitsubishi Heavy Industries, Ltd. (MHI) have jointly developed and evaluated the MOLB type SOFC since 1990. In 1992,the maximum out put of 1.32kW was recorded on 150mm×150mm 40-cell 3stacks. In 1996,We obtained 5.1kW on 200×200mm 40-cell 2stacks. From 1997,the development of 25kW module was started. The design and materials improved. We started for 25kW module generation test in August, 2000.
