Zusammenfassung:	The disclosure relates to a method for controlling a polymer electrolyte membrane fuel cell. The fuel cell is installed in a system which comprises a fuel gas supply circuit that links a fuel gas reservoir to the anode of the fuel cell. The system also has an oxidant gas supply circuit linking an oxidant gas reservoir, or atmospheric air. The method includes the step of supplying the fuel cell with oxidant gas. The method proceeds with the step of detecting that the current produced by the cell is greater than a first threshold determined on the basis of the system in which the fuel cell is installed. The method continues with the step of reducing the supply of oxidant gas to the fuel cell in order to reduce the current that is produced.
