METHOD FOR INCREASING THE SAFETY AND/OR THE RELIABILITY OF THE OPERATION OF A FUEL CELL STACK

摘要

A method (400) for increasing the safety and/or the reliability of the operation of a fuel cell stack (101) is described. The method (400) comprises determining (401) that the fuel cell stack (101) is in a space (200) with a reduced air exchange rate (221). The method (400) also comprises determining (402) consumption information with respect to an oxygen consumption of the fuel cell stack (101) within an interval of time. The method (400) also comprises determining (403), on the basis of the air exchange rate (221), inflow information with respect to an amount of oxygen which was supplied to the space (200) within the interval of time. The method (400) also comprises determining (404) an estimated value for an oxygen content of air in the space (200) on the basis of the consumption information and on the basis of the inflow information.
