    • 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.
    • 本发明提供一种用于通过分析燃料电池堆的最小电池电压来实时确定电极表面中的冰块发生的方法,同时,区分阳极中的冰块的发生与 阴极中的阻冰。 在优选的方面,本发明提供了一种用于检测燃料电池堆的冰块阻挡的方法,所述方法包括:(a)根据由电池电压监测系统测量的电池电压周期性地计算燃料电池堆的最小电池电压,同时反应物 气体被供应到燃料电池堆; (b)使用当前计算的最小电池电压和先前的最小电池电压来计算最小电池电压的变化; (c)确定最小电池电压的变化是否高于预定的参考值; 以及(d)当最小电池电压的变化高于参考值时,确定在燃料电池堆的阳极中发生冰块阻塞。
