<P>PROBLEM TO BE SOLVED: To control performance deterioration of a fuel cell in the fuel cell system. <P>SOLUTION: The fuel cell system having a fuel cell is provided with an anode exhaust gas circulation portion which re-supplies an anode exhaust gas discharged from the fuel cell to the fuel cell, an anode exhaust gas discharge portion which discharges the anode exhaust gas in the anode exhaust gas circulation portion, a power generation shutdown portion which stops power generation of the fuel cell, and a control portion which, when stopping power generation of the fuel cell, stops circulation of the anode exhaust gas by controlling the anode exhaust gas circulation portion while continuing power generation of the fuel cell, as a pretreatment of power generation shut-down, and thereafter, discharges the anode exhaust gas by controlling the anode exhaust gas discharge portion, and stops power generation of the fuel cell by controlling the power generation shutdown portion. <P>COPYRIGHT: (C)2011,JPO&INPIT |
