Undetected gas leaks in a fuel cell can lead to a fire inside the fuel cell and thus to the destruction of said fuel cell. The invention relates to a method for localising a gas leak inside a fuel cell system (1) comprising a number of fuel cells. After supplying (21) the fuel cells with the fuel gase s, the fuel gas supply to at least one of the two gas chambers of the fuel cell s is interrupted (25), the gas chamber which is separated from the fuel gas supply is rinsed with an inert gas (29), the fuel cells are brought into electrical contact (31) with a discharging resistor (13) or are already in contact therewith, and the cell voltage of the fuel cells is monitored.</SDO AB> |
