摘要： The present invention relates to a fuel cell system including a fuel cell, a hydrogen gas piping system for supplying a hydrogen gas to the fuel cell, an injector which adjusts a gas state on an upstream side of the hydrogen gas piping system to supply the gas to a downstream side, and a control device which drives and controls the injector in a predetermined driving period, wherein a driving characteristic of the injector is learnt, and a driving parameter of the injector can be set based on a result of the learning. In the present invention, during an operation of the fuel cell, a supply pressure of the hydrogen gas can appropriately be changed in accordance with an operation state. In addition, even when the pressure is broadly varied, a satisfactory pressure response property can be secured regardless of fluctuations due to aging and individual difference of the injector.

摘要： Provided is a vehicle skid control device that avoids a skid erroneous judgment in a high revolution range of a motor. The vehicle skid control device detects the number of revolutions of the motor. When the number of revolutions of the motor is equal to or larger than a predetermined threshold value Nm, the vehicle skid control device prohibits a skid judgment. When the number of revolutions of the motor is smaller than the predetermined threshold value Nm, the vehicle skid control device permits the skid judgment. When the number of revolutions of the motor is equal to or larger than the threshold value Nm, the skid judgment is prohibited. Accordingly, it is possible to avoid the skid erroneous judgment in the high revolution range with the number of revolutions equal to or larger than Nm.

摘要： In the present invention, after the initial setting of the FC entry target pressure, the FC entry target pressure is maintained at this initial-setting value until the concentration of impurities in the gas supplied to the anode in the fuel cell falls below a certain value. This initial-setting value is set to a pressure higher than the FC entry target pressure set in response to the FC electric current during normal power generation. If the concentration of impurities in the gas supplied to the anode in the fuel cell has fallen below the certain value, then the FC entry target pressure is sought using a map showing the relationship between the FC electric current detected in step S5 and the entry target pressure set in response to the output required for the fuel cell.

摘要： When a request power for a fuel cell is smaller than a predetermined value, a fuel cell system stops the supply of an oxidizing gas to the fuel cell and lowers the output voltage of the fuel cell from a use upper limit voltage to a reduction voltage to perform catalyst activation processing. When the output voltage of the fuel cell lowers to an air blow voltage because of the shortage of the oxidizing gas, the fuel cell system re-supplies the oxidizing gas to recover the output voltage of the fuel cell.

摘要： To provide a fuel cell system that can both improve power generation efficiency of a fuel cell and maintain durability of the fuel cell. A fuel cell system performs control such that when a power requirement for the fuel cell is lower than a predetermined value, a supply of a reaction gas to a fuel cell is stopped to keep an output voltage from the fuel cell equal to a high-potential avoidance voltage that is lower than an open end voltage. The fuel cell system further controls the output voltage from the fuel cell with the high-potential avoidance voltage set to be an upper limit when the power requirement for the fuel cell is equal to or higher than a predetermined value. By setting the upper limit of the output voltage of the fuel cell to be the high-potential avoidance voltage, which is lower than the open end voltage, the catalyst can be inhibited from being degraded by an increase in the output voltage from the fuel cell up to the open end voltage.
