摘要： In a fuel cell system, regeneration-time voltage fixed control is implemented where during regeneration or when regeneration is expected to occur, output voltage of a fuel cell is set to a voltage value outside an oxidation reduction progress voltage range, and the amount of reactant gas supplied to the fuel cell is changed based on the amount of electric power remaining in an energy storage device. In the regeneration-time voltage fixed control, it is determined whether or not regeneration occurs while a moving body equipped with the fuel cell system is moving down a slope, and in the case where it is determined that regeneration occurs while the moving body is moving down a slope, the amount of the reactant gas supplied to the fuel cell is decreased in comparison with the case where it is determined that regeneration occurs while the moving body is not moving down a slope.

摘要： When the output of a fuel cell starts to decrease, in consideration of the increase in the power generation efficiency, an instruction for the output of the fuel cell undergoes a smoothing process to gradually decrease the output, and excessive electric power generated during a period in which the power generation efficiency is high is used for charging a battery. While the output of the fuel cell is increasing, the power generation efficiency of the fuel cell is low. Thus, assisting electrical energy from the battery is increased. In this manner, the power generation output when the power generation efficiency of the fuel cell is low is reduced from a high power generation output to a low power generation output to achieve improvement in the average power generation efficiency.

摘要： A fuel cell vehicle capable of improving energy efficiency by reducing switching loss is provided. The fuel cell vehicle includes: a fuel cell that generates direct current power; inverters which respectively include switching elements and convert the direct current power generated by the fuel cell into alternating current power; a diode that prevents current from flowing from the inverters toward the fuel cell; a step up/down DC/DC converter that adjusts the voltage of the cathode side of the diode; a voltage control part that controls the step up/down DC/DC converter, thereby controlling current output from the fuel cell; and a stop and idle determination part that stops the supply of air to the fuel cell, thereby stopping idling of the fuel cell. The voltage control part reduces the voltage of the cathode side of the diode as the voltage of the fuel cell is reduced by activating the stop and idle determination part.

摘要： A management ECU of a control unit predicts the reduction degree of a system voltage according to an operational state of a motor based on the temperature of a fuel cell and a number of rotations of the motor, sets motor output restriction start voltage and motor output restriction end voltage which are threshold values of the system voltage for triggering an execution start and an execution end of a processing to restrict an output of the motor, and outputs them to a motor ECU. The motor ECU sets an output restriction coefficient that is a restriction rate in restricting the output of the motor based on a detected value of the system voltage and the motor output restriction start voltage and the motor output restriction end voltage, and restricts the output of the motor.
