The basic principle of electrolytic reaction of membrane electrolysis cell is to convert electric energy into chemical energy and electrolyze brine to produce NaOH, Cl2 and H2 as shown in the above picture. In the anode chamber of the cell (on the right side of the picture), the brine is ionized into Na+ and Cl- in the cell, wherein Na+ migrates to the cathode chamber (left side of the picture) through a selective ionic membrane under the action of charge. The lower Cl- generates chlorine gas under anodic electrolysis. The H2O ionization in the cathode chamber becomes H+ and OH-, wherein OH- is blocked by a selective cation membrane in the cathode chamber and Na+ from the anode chamber is combined to form product NaOH, and H+ generates hydrogen under cathodic electrolysis.
