  • Method of monitoring a fuel cell unit
    Patent number: 7124040
    Abstract: In a method of monitoring a fuel cell unit, at least one pair of measured values, including a measured current value and a measured voltage value (Iactual, Uactual) are determined at the outputs of the fuel cell unit. The measured voltage value (Uactual) is compared with a limit value (PG), which is a function of the measured current value (Iactual) by way of a limit characteristic polarization curve. It is concluded that the condition of the fuel cell unit is faulty when the measured voltage value (Uactual) or a function of the measured voltage value is smaller than or equal to a predefined threshold value.
