Background

Electrolytic cells are commonly used to produce a variety of chemicals, and one of the applications of electrolytic cells is the production of ozone, which is considered an effective disinfectant because it is effective in killing pathogens and bacteria. Meanwhile, the prior art has applied the electrolytic cell to a plurality of fields of generating ozone water, and using the ozone water for medical care disinfection, household sanitation cleaning disinfection, plant and breeding industry disinfection, sewage treatment, and the like.

The basic structure of the existing electrolytic cell for producing ozone or ozone water is that the electrolytic cell consists of an anode and a cathode or consists of an anode, a cathode and a membrane which is clamped in the anode and plays a role of proton exchange, wherein the membrane plays other roles and is not clamped in the electrode. In the latter case, the membranes which function for proton exchange are often single and have the same technical characteristics. The proton exchange efficiency of the proton exchange membrane and the influence of the proton exchange membrane on the running water in the electrolytic chamber can greatly influence the concentration and efficiency of ozone or ozone water prepared in the electrolytic chamber. Obviously, the stronger the proton exchange capacity of the proton exchange membrane, the larger the contact area between the proton exchange membrane and water, the better the water carrying capacity, the lower the indirect energy consumption, and the better the performance of the corresponding electrolysis chamber.

Meanwhile, in the process of preparing ozone or ozone water by electrolyzing water in the electrolytic cell, the distance between the two electrodes and the membrane also determines the speed and efficiency of proton exchange on the proton exchange membrane to a certain extent.

In addition, in the field of ozone production using an electrolytic cell, the problem of scale treatment on the surface of an electrode has become a hot issue of general research in the field.
