摘要： 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.

摘要： Provided is a fuel cell system which can measure an air blow interval and consider an exceptional condition such as a high-potential-avoiding operation, thereby enabling an accurate judgment of degradation of an electrolyte. An actual air blow time interval is measured while estimating a theoretical air blow time interval when an increase of a hydrogen consumption amount corresponding to a cell voltage in the high-potential-avoiding operation according to an output current by using a relationship table which contains a record of a relationship between a hydrogen consumption amount consumed for maintaining the function of a fuel cell and the air supply time interval varying with the increase of the hydrogen consumption amount. The degradation of the electrolyte of the fuel cell is judged according to whether the measured actual air blow time interval is shorter than the theoretical air blow time interval corresponding to the hydrogen consumption amount.

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： When an output voltage of a fuel cell is lowered to carry out a catalyst activation process so as to activate a catalyst during an intermittent operation of the fuel cell, if generated power P1 exceeds allowed battery charge power, while generated power P2 does not exceed the allowed battery charge power, then low speed corresponding to the generated power P2 is selected and the output voltage of the fuel cell is decreased toward a target voltage on the basis of the low speed, which has been selected, thereby restraining sudden generation of surplus power caused by a reduction in the output voltage of the fuel cell. By the control described above, a voltage reduction speed of a fuel cell is determined according to a receiving capability of an object which receives surplus power generated by the fuel cell during the catalyst activation process of the fuel cell.
