Electric Power Development Co., Ltd. (EPDC) and Mitsubishi Heavy Industries, Ltd. (MHI) have succeeded in the continuous internal reforming 755 hours operation of a pressurized 10kW class module in August 2001. Compressed natural gas was used as fuel. In 1989,we started the development of the module of tubular type Solid Oxide Fuel Cells (SOFC). In 1998,we developed a pressurized 10kW class module, which was operated for 7,000 hours (continuously)^<(1)>. This module does not need heating supports to maintain the operating temperature, and its maximum power output was 21kW and the efficiency was 35% (HHV as H_2) at 75% fuel utilization without fuel recycle system. On the other hand, MHI has developed a new fabrication technology to reduce the cell cost. Instead of plasma spray coating method, co-sintering method was adopted in the new fabrication technology. In 2001,we developed the pressurized internal reforming type 10kW class module, and its operating power output was 11kW and the system efficiency was 41.5% (HHV). Steam for internal reforming was supplied by recycled fuel exhaust.
