The invention relates to a method for operating a fuel cell system, wherein hydrogen from a tank (21) and recirculated hydrogen from a recirculation circuit (50) are supplied to at least one fuel cell (101) via a fuel line (20) as anode gas, and in which the anode gas is removed from the recirculation circuit (50) by intermittently opening a purge valve (41), characterized in that the following steps are carried out: opening or closing the purge valve (41) sensing the pressure in the fuel line (20) upstream of a hydrogen metering valve (51), checking whether a sensed pressure profile matches the opening and/or closing of the purge valve (41). The invention further relates to a control device (27) for carrying out the method or individual method steps.
A method for operating a fuel cell system (1), wherein hydrogen from a tank (21) and recirculated hydrogen from a recirculation circuit (50) are supplied to at least one fuel cell (101) via a fuel line (20) as anode gas, and in which the anode gas is removed from the recirculation circuit (50) by intermittently opening a purge valve (41),
A control device configured to control a fuel cell system (1), wherein hydrogen from a tank (21) and recirculated hydrogen from a recirculation circuit (50) are supplied to at least one fuel cell (101) via a fuel line (20) as anode gas, and in which the anode gas is removed from the recirculation circuit (50) via a purge valve (41), by
