Abstract
In a method for regulating a fuel cell stack (), a current-voltage characteristic of the fuel cell stack is detected and evaluated to determine an operating point of the fuel cell stack, wherein a current-voltage characteristic of the fuel cell stack () is detected at time intervals in operation whose gradient has a minimum, a characteristic value (R) for the minimum of the gradient is respectively determined from the detected current-voltage characteristic and a desired value for the operating point is determined by addition of a predefined offset value (R) to the characteristic value, and wherein the fuel cell stack () is regulated by the desired value determined in this manner.
