<P>PROBLEM TO BE SOLVED: To provide a fuel cell generator system in which in the case of occurrence of leakage of combustible gas in a cabinet, an unstable state can be avoided rapidly, and when it returns to normal conditions, complete safety can be resumed. <P>SOLUTION: The first power supply 11 in order to operate an outdoor temperature measurement means 13, an air exhausting means 15, a gas concentration measurement means 14 to measure concentration of a combustible gas, and a controller 16, and the second power supply 12 in order to operate a hydrogen generating device 17, a stack 9, an exhaust heat recovering means 18, and a gas supply controller 19 are separately installed. When the combustible gas concentration measured by the gas concentration measurement means 14 reaches a prescribed concentration threshold or more, the controller shuts down supply of a raw material gas to the hydrogen generation device 17 by the gas supply controller 19, and the raw material gas or the fuel gas leaked into the space inside the cabinet 8 is exhausted outside the cabinet 8 by the gas exhausting means 15, and the second power supply 12 is turned off by a cutting-off means 10. <P>COPYRIGHT: (C)2011,JPO&INPIT |
