Abstract

L’invention concerne une plaque bipolaire constituant la première plaque polaire d’un premier élément de base d’une pile à combustible et la deuxième plaque polaire d’un deuxième élément de base adjacent au premier élément de base de la même pile à combustible, la plaque bipolaire comprenant deux plaques minces parallèles assemblées par brasure, chaque plaque mince comportant au moins un canal de distribution de carburant ou de comburant ménagé dans l’épaisseur de la plaque polaire, et un canal d’étanchéité destiné à accueillir un joint, également ménagé dans l’épaisseur de la plaque, la plaque bipolaire étant caractérisée en ce que le canal d’étanchéité présente, sur sa surface interne, des excroissances dont la hauteur représente moins de 50% de l’épaisseur du canal d’étanchéité, et dont la surface représente moins de 50% de la surface totale du canal d’étanchéité Figure pour l’abrégé : Fig 3The invention relates to a bipolar plate constituting the first pole plate of a first base element of a fuel cell and the second pole plate of a second base element adjacent to the first base element of the same fuel cell, the bipolar plate comprising two parallel thin plates assembled by brazing, each thin plate comprising at least one fuel or oxidant distribution channel formed in the thickness of the pole plate, and a sealing channel intended to receive a joint, also formed in the thickness of the plate, the bipolar plate being characterized in that the sealing channel has, on its internal surface, protuberances the height of which represents less than 50% of the thickness of the sealing channel, and whose surface represents less than 50% of the total surface of the sealing channel Figure for the abstract: Fig 3
