Technical Field

The utility model relates to an electrolytic cell structure.

Background

An aqueous solution containing ozone and other oxidizing groups can be prepared by using water or an aqueous electrolyte as a raw material and using an electrolyzer. The existing electrolytic cell for preparing ozone or ozone water is basically composed of an anode and a cathode or composed of an anode, a cathode and a membrane which is clamped between the anode and the cathode and plays a role of proton exchange, wherein the membrane which plays other roles is not clamped between the electrodes.

The proton exchange membrane has the following functions: firstly, providing a hydrogen ion channel, namely transferring H & lt + & gt generated by an anode to a cathode through a proton exchange membrane; and secondly, isolating products generated by the two electrodes to prevent reverse reaction. The proton exchange membrane has to work in a wet state, and has good proton conductivity under the condition of containing sufficient moisture, the conductivity of the proton exchange membrane almost has a linear relation with the water content of the membrane, the larger the contact area of the proton exchange membrane and water is, the better the water carrying capacity is, the stronger the proton conduction capacity of the proton exchange membrane is, the lower the indirect energy consumption is, and the better the performance of the corresponding electrolytic chamber is. In some existing electrolytic cell structures provided with a proton exchange membrane, the proton exchange membrane clamped between the anode and the cathode has a small water receiving area, so that the proton conduction efficiency of the proton exchange membrane is poor. How to maintain the wettability of the proton exchange membrane and enable the proton exchange membrane to maintain high-efficiency conductivity becomes a problem which needs to be solved urgently.
