A membrane electrolysis cell, particularly suited for producing chlorine, caustic soda and hydrogen by the electrolysis of brine, has its cathode formed by a static bed of a packing material capable of withstanding the cathodic conditions confined between the membrane and a current distribution-baffle...
In the electrolysis of sodium chloride brine, the invention utilizes the hydrogen gas generated within the cathode compartment to raise the catholyte caustic soda liquid through a riser pipe from the top of a preceding cathode compartment to a disengaging device wherein the hydrogen is separated fro...

With the wide application of alkaline water electrolysis [5,6,7], advanced electrochemical technology [8], brine electrolysis technology in seawater desalination, chlor-alkali industry, and wastewater disposal [9], concentration followed by electrolysis becomes one of the most promising ways for saline...
Figure 1. Schematic diagram of a CSSS-powered SOEC for hydrogen production. To simplify the subsequent analyses, several basic model assumptions are made: (1) The hybrid system operates continuously under stable and consistent conditions; (2) All wavelengths of sunlight entering the system are utili...
On a smaller scale, small units used for swimming pool water treatment, for example, allow the production of low-concentration bleach (0.3 to 1 wt% active chlorine) by use of a direct electrolysis of sodium chloride brine. The oxidation and degradation reaction of hypochlorite ion (ClO−) ...
