Procedure for detecting the permeability state of the polymeric ion-exchange membrane of a fuel cell stack, in which, as soon as the pressure difference in the anode and cathode circuits drops to a value below a threshold value PS, the pressure variation in said circuits for a predetermined time period tC is measured and the pressure difference in these circuits at the end of a predetermined time period, called the control pressure PC, is calculated and a warning is given when the control pressure PC is below a warning threshold PA. |
