Abstract
Procedure for detecting the sealing state of a fuel cell stack in which, as soon as the fuel cell stack is considered to be extinguished, the sum of the pressures in the anode circuit and in the cathode circuit equal to Pis recorded. After an additional period of time of 180 seconds, the sum of the pressures in the anode circuit and in the cathode circuit equal to Pis recorded. If Pis less than P, an alarm is triggered.
