<P>PROBLEM TO BE SOLVED: To properly reduce energy consumption at the dilution, enabling to carry out starting economically. <P>SOLUTION: A controller 21 to constitute a fuel cell system 10 is equipped with an anode gas replacing device 82 for replacing hydrogen in the anode flow passage 36 via an anode gas supply device 16; a soak-time detector 84 to detect a soak time in which the operation of a fuel cell stack 12 is made to stop; and a cathode gas flow control device 86 makes the cathode gas flow amount supplied from the cathode gas supply device 14 replace, according to the soak time, when the hydrogen is to be replaced by the anode gas replacing device 82. <P>COPYRIGHT: (C)2010,JPO&INPIT |
