<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which a duct on the upstream side of a circulation pump can be prevented from being collapsed by a negative pressure even if it is formed of a flexible hose, a factor of cost increase does not occur, and assemblability does not deteriorate. <P>SOLUTION: In fuel cell system FCS, an upper limit is provided on the number of revolutions of a cooling water pump CS2 when the temperature of cooling water at the time of start-up or in the duct goes below a threshold temperature, and the cooling water pump CS2 is operated at a number of revolutions not exceeding the upper limit number of revolutions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
