Abstract

Les piles à combustible à membrane électrolytique polymère (PEM) possèdent en tant qu'unité modulaire essentielle une unité membrane / électrodes (MEA) comportant une cathode et une anode placées de chaque côté d'une membrane polymère, ainsi qu'une chambre cathode et une chambre anode qui sont fermées toutes deux des deux côtés par une plaque bipolaire. Dans la pratique, il peut arriver qu'à l'état de repos de la pile, au cas où aucun courant n'est prélevé, la résistance de l'unité membrane / électrodes (MEA) augmente rapidement. Selon la présente invention, au lieu d'air, une quantité limitée d'hydrogène ou d'un gaz contenant de l'hydrogène est acheminée vers la cathode et la réaction catalytique provoque une recombinaison de l'hydrogène et de l'oxygène, avec formation d'eau et de chaleur. Il est ainsi possible d'humidifier la membrane polymère et de réduire sa résistance de manière ciblée. En vue de la surveillance, un dispositif de mesure (8) de la résistance ohmique peut commander un dispositif de commutation (7) des gaz de processus pour l'humidification de la membrane, via un dispositif de commande et de régulation (5, 6).
