| 摘要 |
The invention relates to a method for detecting the permeability state of the ion exchanger polymer membrane of a fuel cell, wherein, as soon as the pressure difference in the anode and cathode circuits falls to a value lower than a threshold value Ps, the pressure variation in said circuits over a pre-determined period of time tc is measured, the value of the pressure difference in said circuits after a pre-determined amount of time, called control pressure value Pc, is calculated, and an alert is made when the control pressure Pc is lower than an alert threshold PA. |
