Abstract
A fuel cell system includes a motor driving a compressor that supplies air to a fuel cell, a turbine assisting the compressor, a bypass valve that opens and closes the bypass flow path, and a controller. When a required air flow rate is equal to or higher than a threshold value, the controller closes the bypass valve and controls the motor to cause the air to flow through the fuel cell at a flow rate corresponding to the required air flow rate. When the required air flow rate is lower than the threshold value, the controller opens the bypass valve to cause the air to flow through the bypass flow path and controls the motor to cause the air to flow through the fuel cell at the flow rate corresponding to the required air flow rate.
