Abstract

L'invention concerne une plaque bipolaire destinée à une cellule électrochimique, notamment à une cellule électrochimique basse température, comportant un canal de distribution (3) et un canal d'alimentation (1) et d'évacuation (2) aboutissant dans ledit canal de distribution, ainsi qu'au moins un canal d'alimentation ultérieur (4) permettant d'alimenter directement un fluide de fonctionnement dans la canal de distribution (3). Ainsi, il est possible d'améliorer le guidage du flux de fluide de fonctionnement. D'une part, la zone du canal de distribution menacée d'assèchement par du fluide de fonctionnement peu humide est réduite de manière régulière. D'autre part, l'émission d'eau de produit fabriquée est améliorée.
