| description | A fuel cell system includes a bypass passage, a flow path selector portion that selects a flow path of oxidation gas, and a valve opening adjusting portion that adjusts an opening of a pressure adjusting valve. Until a rotation speed of a rotary shaft reaches a separation rotation speed at which the rotary shaft is separated from an aerodynamic bearing, the flow path selector portion permits flow of the oxidation gas from an electric compressor to a fuel cell stack through a supply passage and flow of the oxidation gas from the electric compressor to a discharge passage through the supply passage and the bypass passage, and the valve opening adjusting portion adjusts the opening of a pressure adjusting valve so that an efficiency of a turbine is maximized by the discharge gas. |
