Title:
EMERGENCY POWER SUPPLY SYSTEM USING FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2007/097314
Kind Code:
A1
Abstract:
An emergency power supply system has a fuel cell system and is linked to a system power supply so that when the system power supply stops, power can be supplied from the fuel cell system to a load. A secondary cell is connected in a DC power supply path between the fuel cell and a power conditioner in the fuel cell system. When the power conditioner detects stop of the system power supply and the fuel cell stops, the fuel cell can be restarted by DC power accumulated in the secondary cell. The DC power supplied from the fuel cell after restart is converted into AC power by the power conditioner and supplied to an emergency load in the state disconnected from the system power supply.
