ABSTRACT:
A discharging circuit can be made compact by forming a discharging path for the fuel cell via a fixed resistor. Even if the operation of a fuel cell is interrupted and/or a control power source for supplying electric power to a controlling circuit is interrupted, the discharging circuit is operated in response to a voltage produced through an electrolysis of the gas which is left in the fuel cell. As a result, the fuel cell can discharge, while the degradation of the fuel cell is prevented.
