Abstract:
A fuel cell system is equipped with a fuel cell, a DC/DC converter that is electrically connected to the fuel cell, and a control unit that controls the supply of a fuel gas and an oxidizing gas to the fuel cell and issues a voltage command to and drives the DC/DC converter to perform high potential avoidance control of restraining an output voltage of the fuel cell from exceeding a high potential avoidance voltage lower than an open circuit voltage. The control unit continues to drive the DC/DC converter so as to perform the high potential avoidance control for a predetermined time after stopping supplying the fuel cell with hydrogen and air in response to the inputting of a system operation stop command.
