Method for purging region e.g. anode compartment of polymer electrolyte membrane fuel cell of motor car, involves introducing pressurized purge gas into fuel cell, where purge gas is produced by reaction of hydrogen and oxygen
The method involves introducing pressurized purge gas into a fuel cell (3) for purging a region e.g. anode compartment (4), of the fuel cell or a fuel cell system (1), where the purge gas is produced by a reaction of hydrogen and oxygen, which is triggered by burning hydrogen and oxygen mixture in p...

| description | The method involves introducing pressurized purge gas into a fuel cell (3) for purging a region e.g. anode compartment (4), of the fuel cell or a fuel cell system (1), where the purge gas is produced by a reaction of hydrogen and oxygen, which is triggered by burning hydrogen and oxygen mixture in presence of a catalyst (13). An anode outlet is connected with environment and/or a water separator during the purging process. The reaction of hydrogen and oxygen takes place in a pressure tank that stays in connection with the region to be purged, over a valve device (10) and/or a diaphragm. The reaction is a controlled detonating gas reaction.
Die Erfindung betrifft ein Verfahren zum Spülen zumindest eines Bereichs einer Brennstoffzelle (3) und/oder eines Brennstoffzellensystems (1) zur Vorbereitung auf einen Start der Brennstoffzelle (3), wobei zum Spülen ein unter Druck stehendes Spülgas verwendet wird. Die Erfindung ist dadurch gekennzeichnet, dass das Spülgas durch eine Reaktion von Wasserstoff und Sauerstoff erzeugt wird. |
