Abstract

Pile à combustible et son procédé de fabrication Pile à combustible (1), comprenant : des plaques (10, 30, 50, 70) empilées, chaque plaque comprenant un bord d’échange respectif pour former une face d’échange (5) ; un collecteur extérieur, fluidiquement connecté à la face d’échange ; et un joint de collecteur (90), encadrant la face d’échange (5) pour assurer une étanchéité de la connexion fluidique. Pour que le joint de collecteur ait une forme mieux maîtrisée et soit plus facile à appliquer, chaque plaque comprend une encoche de centrage respective, adjacente au bord d’échange, pour former une rainure de centrage (6) bordant la face d’échange. Le joint de collecteur comprend une portion de joint longitudinale (91) formée dans la rainure de centrage et assurant l’étanchéité de la connexion fluidique. Figure pour l'abrégé : Figure 2
