A fuel cell system which supplies power to an external load with a storage cell and a fuel cell includes, an oxidant feeder configured to supply an oxidant to the fuel cell, an oxidant passage which communicates with the fuel cell and along which the oxidant supplied from the oxidant feeder flows, a bypass passage which branches from the oxidant passage upstream with respect to the fuel cell and along which part of the oxidant supplied by the oxidant feeder flows so as to bypass the fuel cell, a bypass valve which is provided in the bypass passage and which adjusts a quantity of flow of the oxidant flowing along the bypass passage, an oxidant quantity-of-flow control unit which is configured to supply, with the oxidant feeder, the quantity of flow of the oxidant corresponding to an amount of electricity required by the fuel cell, and an oxidant quantity-of-flow control unit for a sound vibration mode configured to supply, with the oxidant feeder, a constant quantity of flow of the oxidant, and further includes a bypass valve control unit configured to control the bypass valve according to a requirement of the fuel cell when the oxidant quantity-of-flow control unit for the sound vibration mode controls the oxidant feeder. |
