Title
(EN) INTEGRAL SCREEN/FRAME ASSEMBLY FOR AN ELECTROCHEMICAL CELL
(FR) ENSEMBLE INTEGRE TREILLIS/TRAME POUR CELLULE ELECTROCHIMIQUE
Abstract
(EN)
An integral screen/frame assembly for use in an electrochemical cell (1) for supporting and facilitating the hydration of a solid membrane (8). The screen/frame assembly is comprised of planar screen layers (75) having the frame (70) disposed about the periphery of those layers such that the frame bonds the layers together.
(FR)
L'invention concerne un ensemble intégré treillis/trame utilisé dans une cellule électrochimique (1) destiné à supporter et à faciliter l'hydratation d'une membrane solide (8). Ledit ensemble comporte des couches de treillis planes (75) dont la trame (70) est disposée autour de leur périphérie de sorte que la trame lie les couches ensemble.
