ELECTROLYSIS CELL WITH ARCHED SUPPORT MEMBERS

WIPO Patent Application WO/2024/056462

A3

Electrolysis cell for chlor-alkali or alkaline water electrolysis comprising two cell elements (2, 3) each defining an electrode chamber (4, 5) by providing a back wall (6) and sidewalls (7) of the electrode chambers (4, 5), an electrode (8, 9) accommodated in each of the electrode chambers (4, 5), a sheet-like separator (10) extending in a height direction (H) and a width direction of the electrolysis cell (1), the separator (10) being interposed in a joint (11) be- tween the two cell elements (2, 3) and providing a separating wall (12) between the electrode chambers (4, 5), and a plurality of support members (13) supporting at least one (8) of the electrodes (8, 9) on the respective back wall (6), wherein the support members (13) each comprise two support portions standing upright on the back wall (6) and extending in the height direction (H) of the electrolysis cell (1), and two foot portions attached to the respec- tive support portion in an angled manner for a planar contact with the back wall (6), wherein the support portions of the support members (13) are connected to each other by an arched portion (18) being arched outwardly towards the supported electrode (8) and providing a re- silient bearing surface (19) for the supported electrode (8), wherein the bearing surface (19) is enlarged upon inwards-directed deflections of the arched portion (18).
