PROBLEM TO BE SOLVED: To provide a fuel cell system for preventing damages that arise due to changes in the electromotive force of a fuel cell which is in operation. SOLUTION: In this fuel cell system, an input signal Sc is inputted to a control unit 18, and a control signal S18a is outputted therefrom. The control signal S18a is supplied to a motor 11 for supplying driving torque S11a thereof to a compressor 12. A positive electrode active material A is compressed by the compressor 12, and a positive electrode active material S12 is outputted therefrom. The positive electrode active material S12 travels by way of a heat exchanger 13, a filter 14, and a pressure sensor 15, thus producing a positive electrode active material S15b. The positive electrode active material S15b is taken into a fuel cell 16 to emit reaction products S16a, 16c, and S16e, in which an electromotive force S16 is generated. The reaction product S16a is pressure-controlled by a pressure-regulating valve 17, on the basis of a level of a control signal 18b and then emitted. When the level of the control signal S18a is lowered, the level of the control signal S18b starts to lower, at a time when a prescribed period of time passes since starting the level lowering of the control signal S18a. |
