Electrolytic cell cathode with zero polar spacing

Abstract

The invention provides an electrolytic cell cathode with zero polar spacing, which comprises a conductive column; a cathode net connected to the conductive column; an elastic net covering the cathode net; a surface net covering the elastic net; a fastening part penetrating through the surface net, the cathode net and the elastic net and is fixed on the conductive column. According to the electrolytic cell cathode provided by the invention, in the using process, the elastic cathode is uniformly attached to the ionic membrane, so that the shaking of the ionic membrane is reduced in the using process, and the service life of the ionic membrane can be greatly prolonged. The elastic net with special structure can effectively prevent the elastic change caused by pressure fluctuation and keep the polar spacing relatively stable. In the process of discharging gas, bubbles can be broken and the resistance inside the electric tank can be reduced. The elasticity of the elastic net is better and more durable, and the current density is uniform.
