METHOD FOR PREVENTING DAMAGE TO A FUEL CELL STACK

The invention relates to a method for detecting a harmful cell voltage (U) of a cell region of a fuel cell stack, wherein the noise (201, 202) of a signal (200) of the cell voltage (U) is determined by means of a cell monitoring process corresponding individually to the fuel cell stack in order to d...

Beschreibung
Zusammenfassung:	The invention relates to a method for detecting a harmful cell voltage (U) of a cell region of a fuel cell stack, wherein the noise (201, 202) of a signal (200) of the cell voltage (U) is determined by means of a cell monitoring process corresponding individually to the fuel cell stack in order to detect harmful cell voltage (U), and a change, in particular a reduction, of the noise (201, 202) with respect to a characteristic noise (201, 202) of the cell voltage (U) is detected as a used signal for a harmful cell voltage (U).
