Abstract
L'invention concerne un empilement de cellules électrochimiques (1) comprenant de multiples cellules électrochimiques (2) qui sont séparées les unes des autres par des plaques bipolaires (5), chaque cellule électrochimique (2) étant formée de deux demi-cellules (3, 4) qui possèdent une membrane (6) en tant que composant commun qui est retenue par un cadre porteur en plusieurs parties (7), le cadre porteur en plusieurs parties (7) étant construit à partir de deux éléments de cadre (16, 17) qui sont empilés l'un sur l'autre, l'insertion d'un agencement de feuille multicouche (9) chevauchant la membrane (6), étant de largeur différente et étant chacune attribuées à une demi-cellule (3, 4), un joint d'étanchéité (14, 15) en contact avec une plaque bipolaire (5) respective étant situé sur l'intérieur de chaque élément de cadre (16, 17) faisant face à l'intérieur de la demi-cellule (3, 4) respective, les deux joints d'étanchéité (14, 15), qui sont décalés l'un par rapport à l'autre en raison de la forme de section transversale différente des éléments de cadre (16, 17), étant chacun en contact avec une couche externe (18, 20) de l'agencement de feuille (9).
