    摘要： The present invention provides a method for determining the occurrence of ice blocking in an electrode surface in real time by analyzing minimum cell voltages of a fuel cell stack and, at the same time, distinguishing the occurrence of ice blocking in an anode from the occurrence of ice blocking in a cathode.In preferred aspects, the present invention provides a method for detecting ice blocking of a fuel cell stack, the method including: (a) periodically calculating a minimum cell voltage of a fuel cell stack from cell voltages measured by a cell voltage monitoring system while reactant gases are supplied to the fuel cell stack; (b) calculating a change in the minimum cell voltage using a currently calculated minimum cell voltage and a previous minimum cell voltage; (c) determining whether the change in the minimum cell voltage is above a predetermined reference value; and (d) determining that the ice blocking occurs in an anode of the fuel cell stack when the change in the minimum cell voltage is above the reference value.

    摘要： Disclosed is a method for detecting ice blocking of a fuel cell stack. In particular, the method includes periodically calculating a minimum cell voltage of a fuel cell stack from cell voltages measured by a cell voltage monitoring system while reactant gases are supplied to the fuel cell stack and then calculating a change in the minimum cell voltage using a currently calculated minimum cell voltage and a previous minimum cell voltage. It is then determined whether the change in the minimum cell voltage is above a predetermined reference value. When the change in the minimum cell voltage is above the reference value, it is determined that the ice blocking has occurred or is occurring in an anode of the fuel cell stack.

    摘要： A method for shutting down a fuel cell system includes: determining whether an outside air temperature is below a first predetermined reference temperature when a shutdown of a fuel cell system is detected; warming up the fuel cell stack by operating balance of plant components of the fuel cell system and a stack load using the power of the fuel cell stack, while the supply of hydrogen to the fuel cell stack is normally maintained, when the outside air temperature is below the first reference temperature; removing water in the fuel cell stack by passing air supplied by an air supply system through the stack load to supply heated air to a cathode of the fuel cell stack; and shutting down the fuel cell system by cutting off the supply of air after the removal of water. The method can eliminate or reduce cold start failure.
