Abstract[English]
The invention relates to an electrochemical cell (1), in particular electrolysis cell or fuel cell, comprising - a membrane (2), - a catalyst layer (3) on either side of the membrane (2) defining an active area (4) and - a frame (5) for one-sided support of the membrane (2) in a peripheral edge area (6), leaving the active area (4) free, whereby the membrane (2) and the frame (5) are connected by positive locking. 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, comprenant - une membrane (2), - une couche de catalyseur (3) de part et d'autre de la membrane (2) définissant une zone active (4) et - un cadre (5) pour un support unilatéral de la membrane (2) dans une zone de bord périphérique (6), laissant libre la zone active (4), la membrane (2) et le cadre (5) étant reliés par verrouillage positif. L'invention concerne en outre un empilement de cellules électrochimiques comprenant au moins une cellule électrochimique (1) selon l'invention.
