Abstract
A fuel cell system installed in a mobile body comprises; a fuel cell; a gas supply flow path; an injection device provided on the gas supply flow path; a pressure regulating valve configured to be provided more on an upstream side than the injection device on the gas supply flow path, and to autonomously perform an opening/closing operation in accordance with a difference between pressure between the pressure regulating valve and the injection device on the gas supply flow path and pressure on an upstream side of the pressure regulating valve; and a control unit configured to control injection of the reaction gas by the injection device. The control unit calculates an injection interval of the injection device based on an upper limit operation count of the pressure regulating valve set in advance with respect to a predetermined traveling distance of the mobile body.
