The fuel cell system includes: a fuel cell that generates electric power upon a supply of a reaction gas; a power storage device that is charged with at least a part of power generated by the fuel cell; and a controller that controls an output voltage of the fuel cell with, as an upper limit, a high-potential avoidance voltage lower than an open end voltage thereof. The controller variably sets the high-potential avoidance voltage in accordance with the amount of charge SOC of the power storage device.

摘要： A fuel battery system which can suppress unexpected variation of a target power during execution of a high potential avoidance control operation. The fuel battery system sets a high potential avoidance target voltage value, converts the high potential avoidance target voltage value into a target power value on the basis of the voltage-power property map of a fuel battery, limits the target power value within a range between a predetermined upper limit value and a predetermined lower limit value, and controls the operation of the fuel battery on the basis of the target power value while limiting the output voltage of the fuel battery to a value which is not larger than the high potential avoidance target voltage. This can suppress the unexpected variation of the target power value resulting from the erroneous estimation of output properties caused by the momentary drop of the high potential avoidance target voltage.

摘要： A fuel cell system capable of providing a suitable power distribution is provided. A fuel cell system includes: a fuel cell that generates electric power through an electrochemical reaction between a fuel gas and an oxidant gas; a motor that can be driven upon the supply of electric power and can generate regenerative power; a power storage unit which can be charged with power generated from the fuel cell and regenerative power of the motor and can discharge charge power to the motor; an auxiliary apparatus used for operating at least the fuel cell; and a control unit that controls a power distribution between the above components. The control unit determines the power distribution using a power generation command value based on power required to be generated during a normal operation, while the control unit determines the power distribution using a power generation measured value of the fuel cell instead of the power generation command value during a high-potential prevention control that avoids a voltage of the fuel cell becoming equal to or higher than a predetermined high-potential prevention voltage threshold lower than an open circuit voltage of the fuel cell.

摘要： To provide a fuel cell system capable of efficiently transmitting electric power output from a battery to a load. A control unit 80 turns a relay 20 off so as to cut off the connection between a fuel cell 40 and an inverter 50 if it is determined that a command indicating that an EV travel mode should be set has been received. Then, the control unit 80 detects an output voltage of the battery 60 on the basis of SOC information supplied from a SOC sensor 65. Further, based on the detected output voltage of the battery 60, the control unit 80 determines an optimum operating voltage at the point of time by taking converter efficiency and inverter efficiency into account.
