Abstract
Provided is a fuel cell system including: a fuel cell that supplies electricity to a load; a fuel cell converter that is connected between the fuel cell and the load and boosts a voltage output from the fuel cell; and a control unit that causes the fuel cell converter to perform a voltage boosting action and controls output electricity to the load. Upon detecting a voltage boosting disabling failure that is a failure in which the fuel cell converter is unable to perform the voltage boosting action and able to pass a current, the control unit stops the voltage boosting action of the fuel cell converter and passes a current through the fuel cell converter.
Claims5
A fuel cell system comprising:
- a fuel cell that supplies electricity to a load;
- a fuel cell converter that is connected between the fuel cell and the load and boosts a voltage output from the fuel cell;
- and
- a control unit configured to cause the fuel cell converter to perform a voltage boosting action, and configured to control output electricity to the load,
- wherein the control unit is configured to, upon detecting a voltage boosting-disabling failure that is a failure in which the fuel cell converter is unable to perform the voltage boosting action and able to pass a current, stop the voltage boosting action of the fuel cell converter and pass a current generated by the fuel coil through the fuel cell converter.
A control method of a fuel cell system having a fuel cell converter that is connected between a fuel cell and a load and boosts an output voltage of the fuel cell, the control method comprising, upon detecting a voltage boosting disabling failure that is a failure in which the fuel cell converter is unable to perform a voltage boosting action and able to pass a current, stopping the voltage boosting action of the fuel cell converter and passing a current generated by the fuel cell through the fuel cell converter.
