<P>PROBLEM TO BE SOLVED: To provide a fuel cell system reducing deterioration of fuel cells. <P>SOLUTION: The fuel cell system mounted on a motorbike includes: a cell stack; a CPU; a voltage detection circuit; a current detection circuit; an external air temperature sensor; a humidity sensor; a concentration sensor; and a sonar. The CPU obtains: a volume of a garage; an amount of temperature change; an amount of humidity change; an amount of methanol concentration change in external air; and an amount of output change in the cell stack, based on detection results from the voltage detection circuit, the current detection circuit, the external air temperature sensor, the humidity sensor, the concentration sensor, and the sonar. The CPU sets first through fifth duration times (S29), based on the volume of the garage and the various amounts of changes, selects the shortest duration time (S35) of the set duration times, and then, stops power generation (S41), in the cell stack when the selected duration time has passed (S39). <P>COPYRIGHT: (C)2010,JPO&INPIT |
