Title (DE) VERFAHREN ZUR REGULATION DES FEUCHTIGKEITSZUSTANDS EINER MEMBRAN EINER BRENNSTOFFZELLE
(EN) METHOD FOR REGULATING THE HUMIDITY OF A MEMBRANE OF A FUEL CELL
(FR) PROCÉDÉ DE RÉGULATION DE L’HUMIDITÉ D’UNE MEMBRANE D’UNE PILE À COMBUSTIBLE
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Regulation des Feuchtigkeitszustands einer Membran (12) einer Brennstoffzelle, umfassend die Schritte des Verdichtens eines Kathodengases (2) mittels eines Verdichters (22) und des Befeuchtens eines Kathodengases (2) durch Zuführen von Wasser zu dem Kathodengas (2) mittels einer Zuführeinrichtung, wobei die Zuführeinrichtung ein Einspritzventil (26) aufweist, über das das Wasser dem bereits verdichteten Kathodengas (2) bedarfsgerecht zugeführt wird.
(EN) The invention relates to a method for regulating the humidity of a membrane (12) of a fuel cell, comprising the steps of compressing a cathode gas (2) by means of a compressor (22) and humidifying a cathode gas (2) by supplying water to the cathode gas (2) by means of a supply device, the supply device comprising an injection valve (26) by means of which the water is supplied to the already compressed cathode gas (2) on demand.
(FR) L’invention concerne un procédé de régulation de l’humidité d’une membrane (12) d’une pile à combustible. Le procédé comprend les étapes consistant à comprimer un gaz cathodique (2) au moyen d’un compresseur (22) et à humidifier un gaz cathodique (2) par alimentation du gaz cathodique (2) en eau au moyen d’un dispositif d’alimentation. Le dispositif d’alimentation comporte une vanne d’injection (26) permettant d’alimenter en eau le gaz cathodique (2) déjà comprimé en fonction des besoins.
