Abstract:
1. A fuel cell system comprising: a fuel cell; a fuel supply system which supplies a fuel gas to the fuel cell; an injector which drives a valve body with an electromagnetic driving force in a predetermined driving period to detach the valve body from a valve seat, whereby a gas state on the upstream side of the fuel supply system is adjusted to jet the gas to a downstream side; and a control device which controls the operation of the injector, wherein the control device allows the injector to jet the gas with a jet flow rate of a predetermined jet flow rate or less in a case where a demanded amount of power to be generated with respect to the fuel cell is a predetermined amount of power to be generated or less, and the control device sets a driving frequency of the injector in accordance with the jet flow rate and the demanded amount of the power to be generated.
