  • Publication number: 20210328239
    Abstract: A fuel cell system includes a fuel cell stack and a control device that controls operation of the fuel cell system based on a measured voltage value measured by a voltage sensor. When the fuel cell system is started and a value measured by a temperature sensor is equal to or less than a temperature determined in advance, the control device raises the voltage of the fuel cell stack until a voltage condition determined in advance is met, by supplying a cathode with an oxidant gas before current sweep is started. The control device sets a voltage command value and a current command value such that an operation point of the fuel cell stack is on an equal power line of the fuel cell stack when the operation point is caused to transition in at least a part of a transition period.

  • Publication number: 20210310686
    Abstract: Each of a plurality of temperature adjustment apparatuses variably adjusts the amount of heat exchange between an inflow medium, which is a liquid medium supplied to a corresponding indoor heat exchanger, and an outflow medium, which is a liquid medium discharged from the corresponding indoor heat exchanger. Each of the plurality of temperature adjustment apparatuses reduces the heat exchanging capacity of the corresponding indoor heat exchanger by increasing the amount of heat exchange between the inflow medium and the outflow medium when the heat exchanging capacity of the corresponding indoor heat exchanger is larger than the indoor load. When there is no temperature adjustment apparatus in which the amount of heat exchange between the inflow medium and the outflow medium is set to the minimum, the heat source apparatus reduces the heating capacity or the cooling capacity for changing the temperature of the liquid medium.

  • Publication number: 20210305950
    Abstract: A radio frequency signal having a constant amplitude is modulated by a digital modulation signal and a radio frequency input signal whose amplitude changes stepwise is generated. The radio frequency input signal is input into a power amplifier that is an evaluation target. A period in which an amplitude of the radio frequency input signal is constant is defined as a measurement period and an output signal of the power amplifier is measured in each of measurement periods in which amplitudes of the radio frequency input signal are different from each other.

  • Publication number: 20210226235
    Abstract: A fuel cell system includes a fuel cell in which cells are stacked, a voltage sensor that detects a voltage in unit of one or more of the cells, a control unit that determines an operating point of the fuel cell and causes the fuel cell to operate. The control unit causes the fuel cell to operate at a low efficiency operating point having a lower efficiency than an efficiency of a reference operating point in a warm-up operation. In the warm-up operation, the control unit calculates a total number of the cells in which the voltage detected by the voltage sensor is equal to or less than a predetermined first reference voltage and calculates an exhaust hydrogen concentration based on the total number or the cells.
