<P>PROBLEM TO BE SOLVED: To provide one kind of a control device of a fuel cell device, and to make the fuel cell device operable under the best operational condition by the control of the control device. <P>SOLUTION: This control device of the fuel cell device is equipped with a microprocessor, a voltage detection circuit, a current detection circuit, a hydrogen gas pressure detection circuit, a temperature detection circuit, an air flow control circuit of pulse width modulation control, and a pulse generation circuit. The air flow control circuit receives the control of the microprocessor, and by an output current value of the fuel cell device, controls a wind volume of a ventilation device inside an air supply tube wire by a control signal of the pulse width modulation. The pulse generation circuit receives the control of the microprocessor, generates the pulse signal, and controls the open and close state of a hydrogen gas valve inside the hydrogen gas supply tube wire of the fuel cell device. By the control of the control device, the operation of the fuel cell device is controlled by set values of prescribed numeric values of a control process and each item. <P>COPYRIGHT: (C)2004,JPO |
