Title:
ION-EXCHANGE MEMBRANE ELECTROLYZER
Document Type and Number:
WIPO Patent Application WO/2010/122785
Kind Code:
A1
Abstract:
An ion-exchange membrane electrolyzer contacts, at an electrode contact portion, with a flat plate spring-like body extending in an electrode direction and integrally formed with a flat plate spring-like body holding member provided in an electrode chamber, and is electrically conducted to the flat plate spring-like body. The flat plate spring-like body has, at a position extending in the same plane as the flat plate spring-like body holding member at a distance from the joint thereof, a portion extending on the opposite side to an electrode with which the flat plate spring-like body contacts and also has a portion extending in the direction of an electrode contacting an end side. The electrode with which the flat plate spring-like body contacts is attached with an expanded metal electrode having a step size of 0.1 mm or more and 0.5 mm or less, a minor axis of 0.5 mm or more and 3.0 mm or less, a major axis of 1.0 mm or more and 6.0 mm or less, and a sheet thickness of 0.1 mm or more and 0.5 mm or less. A value obtained by dividing an area given by the product of lengths in short and long directions of a mesh of the expanded metal electrode by the number of contact portions between the flat plate spring-like body and the electrode contact portion is 0.01 to 10 cm2. A reaction force per electrode contact portion is 0.1 to 4.0 N.
