AZEC-B1 Electrolytic Cell

Electrode Modification

The cathode is retrofitted using a structure comprising a cathode bottom mesh, an elastic mesh, and an active cathode mesh. During the retrofit, the electrode spacing must be strictly controlled. Optimization of the cathode installation method: the conventional nickel-strip welding approach for installing the cathode-side electrodes has been upgraded to a new cathode encapsulation design. The nickel strip has been eliminated, and the active surface mesh of the cathode is now subjected to a edge-sealing process.

Methods for Zero-Cell-Spacing Retrofit of Electrolyzers

Single-thread hooking weaving
By increasing the diameter of the nickel-based substrate wire from 0.155 mm to 0.18 mm, the material achieves high strength, excellent resistance to pressure fluctuations, and long service life. This is critically important because, in the zero-gap design of electrolyzers, there are no welds between the elastic mesh and the active mesh; electrical conduction between them relies solely on physical contact. If the elastic mesh loses its elasticity, effective electrical conduction between the two meshes will be compromised, leading to conductivity issues in zero-gap electrolyzers.
Ensure that, throughout the entire service life of the cathode coating, the distance between the cathode and the ion-exchange membrane remains in full contact at all locations.
Therefore, the dimensions of the elastic mesh and the corrugation spacing may vary depending on the type of electrolyzer or, for electrolyzers of the same type but with different electrode spacings.

Hazards Caused by Broken Filaments in Elastic Nets and Mitigation Measures

Puncturing the ion-exchange membrane to create pinholes results in electrode corrosion, leading to coating damage.
Increasing wire diameter to enhance mechanical properties, designing a rational mesh configuration, and optimizing roll equipment.

The conventional nickel-strip fixation method has been abandoned in favor of an innovative cladding approach for securing the cathode mesh.

The pin design eliminates the frequent solder joint failures associated with nickel straps, which can hinder maintenance of the electrolytic cell during inspections and repairs.
The new fixing method promotes smooth gas flow and reduces the tendency for gas to accumulate.
The nickel-increase band is prone to causing localized compression on the ion-exchange membrane, resulting in damage.
