Abstract
A fuel cell system includes a fuel cell, a motor connected to the fuel cell, an FC boost converter which raises the output voltage of the fuel cell to output the voltage to the motor, an inverter, and a controller which controls the fuel cell, the FC boost converter and the inverter. When abnormality occurs in one of the FC boost converter and the inverter, an abnormality signal does not pass through a converter control unit or an inverter control unit but is transmitted to the other device, thereby enabling the stop of both the FC boost converter and the inverter.
