ABSTRACT:
Electronic equipment includes a fuel cell for supplying electrical power. A power source switch controls supply of power to the electronic equipment. A voltage check unit compares a voltage of the fuel cell with a reference voltage and generates a voltage depleted signal when such voltage is below the reference voltage. A control unit measures from a time when the supply of power of the fuel cell to the electronic equipment is stopped to a time when the supply of the power of the fuel cell to the electronic equipment is started, and controls the voltage check unit to operate according to a first reference voltage if the measured time is shorter than a predetermined time. If the measured time is longer than the predetermined time, the voltage check unit is controlled to operate according to a second reference voltage.
