New Power Supply System Using UPS Integrated with Fuel Cell Power Plant

摘要

Fuel cell power plants have been attracting attention in recent years as an ecological power system. The number of PC25_(TM)C fuel cell power plants in operation has been increasing because of the high efficiency and environment friendliness of this system. Tokyo Gas Co.,Ltd., Oosaka Gas Co.,Ltd., Toho Gas Co.,Ltd., and Toshiba have Jointly developed a new secure power system integrating an uninterruptible power system (UPS) with a PC25_(TM)C fuel cell power plant. This system permits simultaneous grid-connected and grid-independent operation, and enables high-quality power to be supplied in the event of grid outage.The system commenced operation in June 2000 at the Toho Gas Co.,Ltd. head office building, and is currently being used as a power source for personal computers.
