Abstract[English]
The present invention provides a method of fixing a separator membrane to a first frame member of a battery cell stack. The method comprises: creating a fixation area comprising a first zone and a second zone, wherein creating the first zone comprises securing the separator membrane to the first frame member, and wherein creating the second zone comprises mechanically compressing the separator membrane with a projection of a frame member or with a sealing part. There is also provided a cell stack and a use of an ion-exchange membrane in the disclosed cell stack.[French]
La présente invention concerne un procédé de fixation d'une membrane de séparateur à un premier élément de cadre d'un empilement de cellules de batterie. Le procédé consiste à : créer une zone de fixation comprenant une première zone et une seconde zone, la création de la première zone consistant à fixer la membrane séparatrice au premier élément de cadre, et la création de la seconde zone consistant à comprimer mécaniquement la membrane séparatrice avec une saillie d'un élément de cadre ou avec une partie d'étanchéité. L'invention concerne également un empilement de cellules et l'utilisation d'une membrane échangeuse d'ions dans l'empilement de cellules selon l'invention.
