A fuel cell system capable of proper driving even at times of low temperature, below freezing or the like. The fuel cell system includes a fuel cell stack (10), piping (24, 44), a pressure regulator (30, 48), and a control unit (16). The piping (24, 44) discharges hydrogen or air that is used in electricity generation from the fuel cell stack (10). The pressure regulator (30, 48) regulates pressure of gases which are supplied and discharged to and from the fuel cell stack in accordance with the size of a load. The control unit (16) judges whether or not there is a likelihood of the pressure regulator (30, 48) freezing, and when it is judged that there is a likelihood of freezing, prohibits a degree of openness of the pressure regulator (30, 48) from going below a predetermined degree of openness. |
