  • Patent number: 11223056
    Abstract: A fuel cell system includes a power supply circuit that supplies electric power from a fuel cell and a secondary battery to the load and charges the secondary battery with electric power from the fuel cell. A decision value acquirer monitors a charge-discharge state of the secondary battery and obtains a decision value that is used to determine a degree of localization of an ion concentration in an electrolytic solution in the secondary battery. When the decision value becomes equal to or greater than a predetermined reference value, a controller limits discharge of the secondary battery. When the decision value is equal to or greater than the reference value and the required power decreases, the controller limits a decrease in output power of the fuel cell and causes the secondary battery to be charged with the electric power corresponding to the limitation imposed on the decrease in output power.

  • Patent number: 10991961
    Abstract: A fuel cell system includes a removal treatment execution unit configured to execute an oxide layer removal treatment that removes an oxide layer generated on a catalyst of a fuel cell. The removal treatment execution unit is configured to execute the oxide layer removal treatment by adjusting a voltage of the fuel cell to be within a predetermined second voltage range lower than a predetermined first voltage range that is lower than an open-circuit voltage, when an operation of the fuel cell system shifts from a first operation, where a current value of the fuel cell is zero and the flow rate is controlled to maintain the voltage of the fuel cell within the first voltage range, to a second operation, where the current value is larger than zero and the flow rate is controlled in response to an output request to the fuel cell.

  • Patent number: 10804553
    Abstract: A fuel cell system according to one embodiment performs refresh control of an electrode catalyst of a fuel cell, by reducing a stack voltage as a voltage of the fuel cell to a refresh voltage at which the electrode catalyst is activated. The system includes the fuel cell that generates electric power by an electrochemical reaction using fuel gas and oxidation gas, a stack voltage sensor that sensors the stack voltage, and a controller that controls power of the fuel cell. When a high load demand that makes the stack voltage lower than a given voltage is made on the fuel cell, the controller causes the fuel cell to deliver power commensurate with the high load demand, and performs refresh control when the stack voltage becomes lower than the given voltage through the above control.
