Summary:The invention relates to a method for checking a fuel cell system (100) for membrane impermeability, the method comprising the following steps: 1) shutting off sub-systems (Q1, Q2, Q3) of the fuel cell system (100) which could be the direct sources of a fuel leakage and/or a fuel mass flow, 2) operating a cathode system (10) for providing an oxygen-containing reactant, 3) operating an anode system (20) for providing a fuel-containing reactant, and 4) monitoring measurement results of the fuel sensor (S).
