The invention relates to a method for operating a fuel cell system (1), hydrogen from a tank (21) and recirculated hydrogen from a recirculation circuit (50) being supplied to at least one fuel cell (101) via a fuel line (20) as anode gas, and the anode gas being removed from the recirculation circuit (50) by intermittently opening a purge valve (41), characterized in that the following steps are carried out: opening the purge valve (41) sensing the pressure drop in the fuel line (20) upstream of a hydrogen metering valve (51), checking whether the valve characteristic of the purge valve (41) matches a molar flow calculated from the pressure drop. The invention further relates to a control device for carrying out the method or individual method steps.
A method for operating a fuel cell system (1), in which hydrogen from a tank (21) and recirculated hydrogen from a recirculation circuit (50) are supplied to a fuel cell (101) via a fuel line (20) as anode gas, and the anode gas is removed from the recirculation circuit (50) by intermittently opening a purge valve (41),
A control device configured to operate a fuel cell system (1), in which hydrogen from a tank (21) and recirculated hydrogen from a recirculation circuit (50) are supplied to a fuel cell (101) via a fuel line (20) as anode gas, and the anode gas is removed from the recirculation circuit (50) by intermittently opening a purge valve (41),
