Abstract[English]
The invention relates to an electrochemical cell (1), in particular an electrolysis cell or fuel cell, with a layered construction, comprising a membrane (2) for separating an anode from a cathode, and - on either side of the membrane (2) - a catalyst layer (3), a porous transport or gas diffusion layer (4) and a bipolar plate (5), wherein the membrane (2) has an edge region (7) extending beyond the catalyst layers (3) and the porous transport or gas diffusion layers (4). The invention is characterized by - a frame part (6) supporting the edge region (7) on one side of the membrane (2) and - a filling element (8) arranged on the side of the membrane (2) facing away from the frame part (6) for holding down the edge region (7). The invention further relates to an electrochemical cell stack comprising at least one electrochemical cell (1) according to the invention.[French]
L'invention concerne une cellule électrochimique (1), en particulier une cellule d'électrolyse ou une pile à combustible, à construction en couches, comprenant une membrane (2) destinée à séparer une anode d'une cathode, et de chaque côté de la membrane (2), une couche de catalyseur (3), une couche poreuse de transport ou de diffusion de gaz (4) et une plaque bipolaire (5), la membrane (2) ayant une région de bord (7) s'étendant au-delà des couches de catalyseur (3) et des couches poreuses de transport ou de diffusion de gaz (4). L'invention est caractérisée par : une partie cadre (6) supportant la région de bord (7) sur un côté de la membrane (2) et un élément de remplissage (8) disposé sur le côté de la membrane (2) opposé à la partie cadre (6) pour maintenir la région de bord (7). L'invention concerne en outre un empilement de cellules électrochimiques comprenant au moins une cellule électrochimique (1) selon l'invention.
