Abstract
A fuel cell system includes a fuel cell stack, an oxygen-containing gas supply apparatus, a fuel gas supply apparatus, a pressure reduction apparatus, and a dilution apparatus. The oxygen-containing gas supply apparatus supplies an oxygen-containing gas to the fuel cell stack. The oxygen-containing gas supply apparatus is capable of supplying the air to the fuel gas flow field at the time of stopping operation of the fuel cell system. The fuel gas supply apparatus supplies a fuel gas to the fuel cell stack. The pressure reduction apparatus suctions gases in the oxygen-containing gas flow field and the fuel gas flow field. The dilution apparatus dilutes the fuel gas suctioned by the pressure reduction apparatus using the air.
