Abstract
A fuel cell system is provided which includes a fuel cell to which fuel gas and oxidizing gas are supplied to generate electricity, a purge valve which purges fuel gas discharged from the fuel cell, a dilutor which mixes the purged fuel gas with the oxidizing gas and purges the purged fuel gas mixed with the oxidizing gas into the atmosphere, and an ECU which stops supply of the oxidizing gas to the fuel cell so as to cause an idle stop and determines whether to permit the idle stop depending on a concentration of the fuel gas in the dilutor.
