An input signal is input to a control portion and a control signal S18a is output. The control signal S18a is supplied to a motor and driving torque of the motor is transferred to a compressor. Cathode active material "A" is compressed by the compressor and cathode active material is sent out. The cathode active material passes through a heat exchanger, a filter and a pressure sensor, and cathode active material is sent out. The cathode active material is taken into a fuel cell and reaction product S16a, S16c and S16e are discharged to generate electromotive force S16. The reaction product S16a is discharged on the basis of a level of a control signal S18b by controlling pressure by a pressure regulating valve. When a level of the control signal S18a is reduced, after a predetermined period of time has passed, the level of control signal S18b starts to be reduced.
