  • Publication number: 20210296667
    Abstract: A fuel cell system includes a fuel cell stack of a plurality of power generation cells and an impedance measuring device for measuring the impedance in the fuel cell stack. When stopping the operation of the fuel cell system, a method for stopping the operation of the fuel cell system operates the plurality of power generation cells to generate electric power, until the impedance value becomes equal to or greater than an objective impedance value. After the impedance value has become equal to or greater than the objective impedance value, the operation stopping method still continues the power generation of the multiple power generation cells for a given period of time.

  • Patent number: 10367213
    Abstract: A method of controlling a fuel cell system includes circulating a coolant through a fuel cell circulation passage in which a fuel cell and a gas liquid separator are provided. A valve is controlled selectively to connect or disconnect the fuel cell circulation passage and an air conditioning equipment circulation passage in which an air conditioning mechanism is provided. The valve is maintained to connect the fuel cell circulation passage and the air conditioning equipment circulation passage to circulate the coolant through the air conditioning equipment circulation passage when it is determined that the coolant includes air bubbles more than or equal to the threshold amount, when the valve connects the fuel cell circulation passage and the air conditioning equipment circulation passage, and when a temperature of the fuel cell is higher than or equal to a threshold temperature even if the air conditioning mechanism stops.

  • Publication number: 20190217783
    Abstract: A rear view mirror assembly can switch the operating mode between a first mode in which the rear view mirror assembly is used as an optical mirror, a second mode in which a first image captured by a camera is displayed on a display screen, and a third mode in which a second image captured by the camera and displayed darker than the first image is displayed on the display screen. An actuator sets the angle of a semitransparent mirror: at a first angle in the first mode; at a second angle greater than the first angle in the second mode; and at a third angle greater than the first angle in the third mode. A controller switches the operating mode of the rear view mirror assembly between the first mode and the third mode based on a signal output from a first light sensor and indicating the illuminance.

  • Patent number: 10177390
    Abstract: In a method for controlling a fuel cell system, a shutoff valve is opened to supply a fuel gas from a storage container to a fuel cell after a fuel cell system shutdown instruction is sent to the fuel cell system so that the fuel cell generates and discharges electricity. The storage container is supplied to the fuel gas supplied from a fuel supply source provided outside the fuel cell system in response to a filling instruction to supply the fuel gas to the storage container. A data signal indicating a state of the storage container is transmitted to the fuel supply source. The shutoff valve is closed and the storage container is supplied to the fuel gas supplied from the fuel supply source if the filling instruction is output while opening the shutoff valve after the fuel cell system shutdown instruction is sent.
