Title:
GASKET FOR ELECTROLYSIS VESSELS, AND ELECTROLYSIS VESSEL USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/015120
Kind Code:
A1
Abstract:
Provided are: a gasket for electrolysis vessels, which makes it possible to accommodate and hold a partitioning film in the inside of an electrolysis vessel by a simple operation, can more reliably prevent the leakage of an electrolytic solution or an electrolytic product gas from the inside of the electrolysis vessel, and can keep the partitioning film in such a state that the partitioning film is held at a position that comes in contact with one of electrodes and is located along the electrode, and therefore can reduce the damage of the partitioning film and makes it possible to use the partitioning film stably for a long period; and an electrolysis vessel. A gasket for electrolysis vessels, which has a first surface that is composed of a picture-frame-shaped thin-film-like frame body and comes into contact with an anode-side metallic frame body and a second surface that comes into contact with a cathode-side metallic frame body, wherein a cut-off portion is formed on one surface selected from the first surface and the second surface, the cut-off portion is formed by thinly cutting off a region including an anode-chamber-side or cathode-chamber side edge into an even thickness and has a step having approximately the same thickness as that of the partitioning film, and the gasket is so configured that an end part of the portioning film can be housed and held in the cut-off portion; and an electrolysis vessel provided with the gasket.
