摘要： A shutdown control method of a fuel cell is provided. The method includes applying power to a controller in a shutdown state and determining, by the controller to which the power is applied, a possibility of moisture freezing based on an estimated outdoor temperature or the temperature of a fuel cell stack. A shutdown of the fuel cell is executed by performing moisture removal from the fuel cell stack in response to determining the possibility of moisture freezing after restart.

摘要： A system and method for controlling operation of a fuel cell are provided. The method includes estimating an effective catalyst amount within a fuel cell stack and monitoring a change in the estimated effective catalyst amount according to time. An irreversible degradation state of the fuel cell stack is determined based on the monitored change in the estimated effective catalyst amount.

摘要： A control method for a fuel cell system is provided to prevent freezing in an air exhaust system of the fuel cell system. The method prevents freezing in the exhaust system by specifying a vehicle condition in which possibility of freezing is high and operating the fuel cell system based on different vehicle-specific standards. The performs air supercharging control based on an ambient temperature and a temperature of cooling water, air supercharging control by applying weights based on inclinations of a vehicle, and a forced heating logic using a COD heater.

摘要： An apparatus and a method for detecting leakage in a hydrogen tank of a hydrogen fuel cell vehicle are provided. Particularly, leakage is detected due to failure of an airtight seal of a solenoid valve in a hydrogen tank based on a change of the sensing value of a high pressure sensor which represents a hydrogen tank pressure during a process of performing a wakeup operation at the time of key-off of a vehicle.

摘要： A method of controlling the temperature of a controller of an electric compressor for an air conditioner in a vehicle is provided, which prevents an excessive increase in temperature of the controller under the control of an output current of the controller. The method includes a temperature-determination stage of detecting the temperature of the controller and determining whether or not the detected temperature is equal to or lower than a reference temperature that is lower than a predefined target temperature by a specified number of degrees when an actuating signal of the air conditioner is generated in a switched-on stage of a vehicle. A current-control stage controls an output current of the controller to decrease the temperature until the detected temperature reaches the reference temperature or lower if the detected temperature is determined to be higher than the reference temperature.
