Abstract
A method increases the safety and/or the reliability of the operation of a fuel cell stack. The method determines that the fuel cell stack is in a space with a reduced air exchange rate. The method determines consumption information with respect to an oxygen consumption of the fuel cell stack within an interval of time. The method determines, on the basis of the air exchange rate, inflow information with respect to an amount of oxygen which was supplied to the space within the interval of time. The method determines an estimated value for an oxygen content of air in the space on the basis of the consumption information and on the basis of the inflow information.
