    Mitsubishi Hitachi Power Systems, Ltd. (MHPS) is developing a combined power generation system by combining a solid oxide fuel cell (SOFC), which is a fuel cell that can operate at high temperature, with other power generation systems including gas turbines. For commercial application of the hybrid system, MHI has been conducting demonstration tests at Tokyo Gas Co., Ltd.'s Senju Techno Station and the operation was started in March 2013. The pressurized-type SOFC-MGT hybrid system brought about by combining the 200-kW-class SOFC with a micro gas turbine (MGT) achieved 4,100 hours of continuous operation for the first time in the world, and exhibited a stable operation state even during the heavy-load season in summer. Based on this accomplishment, a new compact-type demonstration system was designed and set up at national university corporation Kyushu University in March 2015. It is planned to be used in demonstration studies and basic research in the future.
