PROCEDURE FOR DETECTING THE STATE OF PERMEABILITY OF THE ION EXCHANGE POLYMER MEMBRANE OF A FUEL CELL

摘要

The present invention proposes an automated procedure for detecting the state of permeability of one or more membranes of a fuel cell pile, sufficiently sensitive to detect the failed membrane, and sufficiently accurate to allow correct maintenance of the fuel cell. This invention is implemented in a fuel cell formed by a pile of electrochemical units each having an anode and a cathode on either side of an ion exchange polymer membrane, the fuel cell having a system for supplying fuel gas on the anode side of the electrochemical units and a system for supplying fuel gas on the cathode side of the electrochemical units.
