摘要： A hybrid control method controls a hybrid vehicle. A control unit sets a rotational speed threshold value at which a continuous gear tooth striking sound occurring in a gear mechanism connecting an electric power generation motor to the internal combustion engine is not a problem in terms of vehicle quality. The control unit generates negative pressure while maintaining the engine rotational speed in the firing state where the engine rotational speed is equal to or greater than the rotational speed threshold value. Also, the control unit generates negative pressure after switching from the firing state to a motoring state where the internal combustion engine is rotated by the electric power generation motor and where the engine rotational speed is less than the rotational speed threshold value.

摘要： A fuel cell system 100 includes: a fuel cell 1 for generating a power by causing an electrochemical reaction between an oxidant gas supplied to an oxidant electrode 34 and a fuel gas supplied to a fuel electrode 67; a fuel gas supplier HS for supplying the fuel gas to the fuel electrode 67; and a controller 40 for controlling the fuel gas supplier HS to thereby supply the fuel gas to the fuel electrode 67, the controller 40 being configured to implement a pressure change when an outlet of the fuel electrode 67 side is closed, wherein based on a first pressure change pattern for implementing the pressure change at a first pressure width ΔP1, the controller 40 periodically changes a pressure of the fuel gas at the fuel electrode 67.

摘要： A fuel cell system can be initiated in shorter time while minimizing the deterioration of a fuel cell. The fuel cell system includes a fuel cell stack having a fuel electrode, an oxidizer electrode and an electrolyte membrane disposed there between, the fuel cell producing electricity by an electrochemical reaction of a fuel gas and an oxidizer gas, which are supplied to the fuel electrode and the oxidizer electrode, respectively; a fuel gas supplying device for supplying the fuel gas to the fuel cell stack; an oxidizer gas supplying device for supplying the oxidizer gas to the fuel cell stack; a current controlling device for extracting a current from the fuel cell stack; and a voltage sensor disposed in at least two of the fuel cell stacks. A controller controls the current controlling device such that a minimum voltage, which is obtained from the voltage sensor after a fuel gas is supplied to the fuel electrode without supplying the oxidizer gas to the oxidizer electrode at the time of initiating, becomes zero volts or more. Then, the oxidizer gas is supplied to the oxidizer to start producing electricity.
