GASKET AND ELECTROLYSER

摘要

Provided are a gasket and an electrolyser capable of preventing an electrolyte or a gas from leaking from a diaphragm. An annular gasket includes first and second surfaces and which respectively contact a frame near a positive electrode and a frame near a negative electrode and a slit portion which is opened inward and is provided in the entire periphery of the gasket so as to accommodate an edge of an ion-permeable diaphragm.

主权项

1. A gasket which is assembled to an alkaline water electrolyser so as to hold a diaphragm and has a square shape or an annular shape, comprising:
first and second surfaces which respectively contact a frame near a positive electrode and a frame near a negative electrode; a slit portion which is opened inward and accommodates the edge of the diaphragm; and a filling portion which is provided outside the slit portion and does not accommodate the diaphragm, first and second portions which face each other with the slit portion interposed therebetween in the facing direction between the first surface and the second surface, the first portion including the first surface and the second portion including the second surface; and a divided portion which is provided in any one of the first portion and the second portion so as to be opened inward and divides the first portion so that the first surface is continuous to a surface defining the slit portion in the first portion or divides the second portion so that the second surface is continuous to a surface defining the slit portion in the second portion, wherein the slit portion and the filling portion are provided in the entire periphery of the gasket.
