How to improve the safety and / or reliability of the operation of the fuel cell stack

摘要

A method (400) for enhancing the safety and / or reliability of operation of the fuel cell stack (101) will be described. The method (400) includes a step (401) of determining that the fuel cell stack (101) is located in the space (200) where the ventilation rate (221) is reduced. In addition to this, the method (400) includes a step (402) of obtaining consumption information regarding the oxygen consumption of the fuel cell stack (101) within a predetermined time interval. Further, the method (400) includes a step (403) of obtaining inflow information regarding the amount of oxygen supplied to the space (200) within the time interval based on the ventilation rate (221). Further, the method (400) includes a step (404) of obtaining an estimate for the oxygen content of the air in the space (200) based on the consumption information and the inflow information.
