ion membrane electrolyzer/membrane electrolyzer

High current density natural circulation bipolar membrane gap electrolyzer

Membrane electrolysis is a process whereby both electrode reactions, i.e. the cathodic reduction as well as the anodic oxidation, are linked to the transport and transfer of charged ions. In membrane electrolysis, the electrode reaction is essential to the actual separation process. The purpose of the membrane is to separate the anode loop (anolyte) from the cathode loop (catholyte) by a fluid, in order to avoid unwanted secondary reactions, so as to combine the electrode reaction with a separation step or to isolate separately the products formed on the electrode. In water electrolysis, such products may be in a gaseous form such as oxygen and hydrogen as well as the acids (H+) and bases (OH-) formed on the electrode or the combination of gaseous chlorine and caustic soda solution and hydrogen as in sodium chloride electrolysis
