<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of enhancing certainty of avoiding an alarm by a warning function for a gas leakage warning of a microcomputer meter. <P>SOLUTION: The fuel cell system 1 is provided with an activity detecting unit (152, 54) for detecting a human activity and an unused time zone estimating unit (110) for estimating an unused time zone of a gas-based device by the activity detecting unit, and a controlling portion 110 maintains, in the unused time zone TO, a gas-supply stopping state for a continuous period of a second prescribed time Tb and controls operation stopping so as to avoid an alarm of a microcomputer meter 200. The controlling portion 110 memorizes a third prescribed time Ta necessary from starting an operation stopping treatment till stopping of the gas supply to a fuel cell module 2, and the controlling portion 110 starts the operation stopping treatment of the fuel cell module 2 at the time going back by the third prescribed time Ta from the starting time of the second prescribed time Tb set in the unused time zone TO. <P>COPYRIGHT: (C)2011,JPO&INPIT |
