摘要： A fuel cell system to be installed on a vehicle includes a fuel cell, a secondary battery, an SOC detector that detects a temperature and a state of charge of the secondary battery, an accelerator position detector that detects an accelerator depressed amount, and a controller that controls power to be generated by the fuel cell. The controller includes: a required generation power calculator that calculates required generation power based on the accelerator depressed amount and the temperature and the state of charge of the secondary battery; and a maximum required power calculator that calculates maximum required power based on the accelerator depressed amount and the temperature and the state of charge of the secondary battery. The maximum required power includes allowable charging power correlated with a maximum value of charging power. If determining that a condition for rapid reduction in consumption power of a motor is satisfied, the controller sets the allowable charging power to zero and calculates the maximum required power. If the required generation power exceeds the maximum required power, the controller makes the fuel cell generate power responsive to the maximum required power.

摘要： There is provided a control method of a flow regulating valve of an oxidizing gas in a fuel cell. In a load disconnected state that the fuel cell is electrically disconnected from a load, the control method gradually opens the flow regulating valve that is configured to supply the oxidizing gas to a cathode of the fuel cell by a predetermined valve opening each time from a full-close position or gradually closes the flow regulating valve by a predetermined valve opening each time from a full-open position, so as to gradually change a supply amount of the oxidizing gas introduced to the cathode and cause hydrogen transmitted from an anode to the cathode in the fuel cell to be oxidized. The control method measures an open circuit voltage of the fuel cell accompanied with oxidation of the hydrogen and stores at least one valve-opening position among valve-opening positions of the flow regulating valve at a predetermined number of timings including a timing when the measured voltage shifts to an increase or shifts to a decrease, as a regulation reference valve-opening timing.

摘要： A vehicle capable of regenerative braking includes a motor that is configured to be driven with electric power. The vehicle selectively sets a drive mode of the vehicle in an accelerator-off state between an ordinary mode and a deceleration enhanced mode that decelerates the vehicle with higher deceleration force than deceleration force in the ordinary mode. The vehicle performs regenerative control of the motor in the ordinary mode or performs deceleration control of generating the deceleration force in the deceleration enhanced mode, in order to decelerate the vehicle in the set drive mode. When an accelerator stroke based on a driver's depression of an accelerator becomes higher than a cancellation threshold in the drive mode set to the deceleration enhanced mode, the cancellation threshold being determined in advance corresponding to the accelerator stroke being greater than zero, the vehicle changes the drive mode from the deceleration enhanced mode to the ordinary mode.

摘要： A vehicle which includes a fuel cell, a receptacle, a lid, and a fixing pin, and which stores a detection of the open state during a period from a time point of a latest end of operation of the vehicle to a time point of input acceptance of a start-up instruction. If a detection of an open state has been stored in a memory at a time point of input acceptance of a start-up instruction, then the vehicle executes a retry operation of temporarily moving the fixing pin of the fixed position to the released position and thereafter moving the fixing pin again to the fixed position during an operating period of the vehicle from the time point of input acceptance of the start-up instruction.
