Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] The electrolytic electrode of the present invention is an electrode used in an electrolytic cell, especially an ion-exchange membrane electrolytic electrode used in an ion-exchange membrane electrolytic cell separated by an ion-exchange membrane into an anode chamber containing an anode and a cathode chamber containing a cathode. In the present invention, the electrolysis electrodes comprise metal perforated plates. figure 1 Shows a schematic partial enlarged view of an electrolysis electrode using a punching mesh punched with diamond-shaped perforations according to a preferred embodiment of the present invention. also, Figure 2A A schematic partial enlarged view of an electrolysis electrode using an expanded metal mesh according to another preferred embodiment of the present invention is shown. Figure 2B shows along the Figure 2A A cross-s...

Abstract

To provide an electrolysis electrode having a more preferable shape in electrolyzing pure water, an alkali aqueous solution, or an aqueous solution of an alkali metal chloride at a lower voltage than ever before, and an electrolyzer using the same. An electrolysis electrode or the like including: a metal perforated plate having a value of Factor V of 40 or more represented by the following formula; Factor V = Rs * Rc * F / 100000, in which Rs is a planar direction surface area per unit area 1 dm2 [cm2 / dm2], Rc is a thickness direction surface area per unit area 1 dm2 [cm2 / dm2], and F is the number of mesh apertures per unit area 1 dm2 (fine degree) [number / dm2].

Description

technical field [0001] The present invention relates to an electrolysis electrode and an electrolysis cell using the electrolysis electrode. In particular, the present invention relates to an electrolysis electrode in an electrolysis cell using a diaphragm and a diaphragm electrolysis cell using the electrolysis electrode. Background technique [0002] In the case of obtaining hydrogen, oxygen or chlorine by electrolysis such as water electrolysis, alkaline water electrolysis or brine electrolysis and alkaline raw materials such as caustic soda, the power consumption rate is reflected in the production of products such as hydrogen, oxygen, caustic soda (NaOH) and chlorine (Cl 2 ) in the cost. In addition, due to the use of electricity in electrolysis, carbon dioxide (CO 2 ) gas, and thus have a negative impact on global warming. In such a social environment, when operating an electrolyzer having a diaphragm or an ion-exchange membrane electrolyzer, an electrolyzer capable...
