Description

technical field [0001] The invention relates to the application field of electrolysis, in particular to a stable strong electric field constant current electrolysis cell and an electrolysis device thereof. Background technique [0002] The basic structure and working principles of electrolysis and electrolyzers have been around for a long time. Electrolyte ions in an electrolytic cell with two levels of yin and yang are often in a disorderly movement. After direct current is applied, the ions move in a directional manner. Cations move to the cathode, get electrons at the cathode, and are reduced; anions move to the anode, lose electrons at the anode, and are oxidized. Electrolysis is widely used in the metallurgical industry to extract metals from ores or compounds (electrowinning) or to purify metals (electrolytic purification), and to deposit metals from solutions (electroplating). Metallic sodium and chlorine gas are produced by electrolytically dissolving sodium chlori...

[0010] Disadvantages: No way to apply minimum potential and control current on anode or cathode for weak electrolytes

[0014] Therefore, in the principle of the existing electrolytic cell, in the process of water electrolysis, the cathode and anode need a large potential difference, OH - It loses electrons at the anode and is oxidized to release oxygen; H + Electrons are obtained at the cathode, which are reduced to hydrogen and released. At the same time, the electrolytic cell consumes a lot of heat energy.
