Detection method for detecting a state of a fuel cell system

Abstract

The present invention relates to a detection method (100) for detecting a state of a fuel cell system (200) comprising a first water separator (201) and a second water separator (203), wherein the first water separator (201) is a main water separator of the fuel cell system (200) and has a main outlet valve (207) for discharging water out of the first water separator (201), wherein the second water separator (205) is integrated into a gas conveyor unit (209) of the fuel cell system (200) and has a flushing valve (211) for flushing the fuel cell system (200), and wherein the first water separator (201) has a greater storage volume than the second water separator (203), wherein the detection method (100) comprises the following steps: opening (101) the main outlet valve (207), operating (103) the flushing valve (211) at regular intervals while the main outlet valve (207) is open, carrying out (105) an empty state detection, outputting (107) a notification, according to which a water store of the second water separator (203) is empty, if an empty state is repeatedly detected by the empty state detection during the regular interval operation.
