Abstract
Provided is a fuel cell system capable of preventing a fuel cell from being polarized at a high potential for a long time during start-up. A fuel cell systemincludes a first injectorA and a second injectorB in a fuel gas inlet passage. When an ECUdetermines that a power generation down time is equal to or more than a predetermined period at start-up of a fuel cell stack, a target pressure of hydrogen supplied to an anode passageis set to be higher for supply than when the power generation down time is less than the predetermined period. In addition, as the power generation down time of the fuel cell stackbecomes longer, the target pressure is set to be higher. Also, a pressure increase in the fuel cell stack is set to be lower than that during ordinary power generation.
