The invention relates to a control device (10) for a fuel cell stack (14), which control device is designed to actuate the fuel cell stack (14) with a predetermined current (IV) and to measure the resulting voltage (U) and to compare it with a reference voltage (UR). The predetermined current (IV) depends on the reference voltage (UR) by a sum of at least two exponential functions, the arguments of which each contain the reference voltage (UR). The control device (10) is designed to determine the reference voltage (UR) by approximately reversing the relationship between the predefined current and the reference voltage (UR) using an iterative approximation algorithm. 本发明涉及一种用于燃料电池堆(14)的控制设备(10)，所述控制设备设置为用于以预给定的电流(IV)来操控所述燃料电池堆(14)并且测量由此得到的电压(U)并且将其与参考电压(UR)进行比较。所述预给定的电流(IV)通过至少两个指数函数的总和取决于所述参考电压(UR)，所述至少两个指数函数的自变量分别包含所述参考电压(UR)。所述控制设备(10)构造为用于，通过利用迭代近似算法近似反转所述预给定的电流与所述参考电压(UR)之间的关系来求取所述参考电压(UR)。
