FUEL BATTERY SYSTEM AND OPERATION METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To shorten a start-up time when a fuel battery system starts up by using only a power source for autonomous start-up.SOLUTION: At a normal startup time, supply of hydrogen-contained gas from a hydrogen generation device 100 to a fuel battery 150 is started while waiting until the temperature of a CO reducer 11 increases to a first lower limit temperature or more. At a blackout startup time at which no power from a system power source is supplied unlike the normal startup time, startup is performed with power of a power source 51 for autonomous startup, and supply of hydrogen-contained gas from the hydrogen generation device 100 to the fuel battery 150 is started while waiting until the temperature of the CO reducer 11 increases to not less than a second lower limit temperature lower than the first lower limit temperature. That is, the temperature condition of the CO reducer 11 when the supply of hydrogen-contained gas from the hydrogen generation device 100 to the fuel battery 150 is performed at the blackout startup time is more relaxed as compared with the temperature condition of the CO reducer 11 when the supply of hydrogen-contained gas from the hydrogen generation device 100 to the fuel battery 150 is performed at the normal startup time.SELECTED DRAWING: Figure 1
