METHOD FOR DIAGNOSING AN IMPENDING POLARITY REVERSEL OF A FUEL CELL

The invention relates to a method for diagnosing a polarity reversal of a fuel cell in a fuel cell system (10). The fuel cell system comprises at least one fuel cell stack (11) having a plurality of fuel cells, as well as a cell voltage monitoring system (20). During a start-up process of the fuel cell system, in particular at cold ambient temperatures, open-circuit voltages of individual fuel cells are detected by means of the cell voltage monitoring system (20), and a reference value is determined on the basis of the detected open-circuit voltages, in particular a mean value of all open-circuit voltages. It is then determined whether a detected open-circuit voltage of at least one of the fuel cells deviates from the reference value, in particular whether the open-circuit voltage is lower than the mean value. If a deviation is detected, an impending polarity reversal of the at least one fuel cell is diagnosed accordingly, which would be expected to occur if an electrical load intended for operation were applied to the fuel cell stack (20). This creates the possibility of optionally modifying, delaying, or, if necessary, even completely preventing the connection of an electrical load. Subsequently, remedial measures, such as heating the fuel cell stack, may be carried out.
