Introduction on Electrode
Electrolysis is a method of using a direct electric current to drive an otherwise non-spontaneous chemical reaction, namely oxidation and reduction, to manufacture required products. As an indispensable part for electrolytic cell, the ion-exchange membrane electrolyzer electrode is an electrical conductor through which electric current enters into or leaves the electrolyte during electrolysis.
The electrode is divided into two types which are anode and cathode. The anode is connected to the positive voltage supply, and oxidation occurs here. The cathode is connected to the negative voltage supply, and reduction occurs here.
Problems of Electrode
During production process, the electrodes can get corroded as a result of different reasons, and this leads to the lowering of electrode activity as well as the increasing of electrode voltage. Thereby, the total power consumption will increase greatly, resulting in a much higher production cost. Under this condition, the manufacturer should analyze the influence of electrode coating failure on the voltage, and recoat the electrode in time to improve the economic benefit and guarantee the safe production.
Depending on the first electrode research laboratory in this industry, namely Wuxi Engineering and Research Center for High-Performance Electrolysis Equipment, we successfully developed two kinds of coating for ion-exchange membrane electrolyzer electrodes, AC11 coating and C11 coating. These coatings possess outstanding features as listed below.
1. They realize lower chlorine evolution potential and hydrogen evolution potential with superb durability.
2. They can offer stable performance for a long time, and are very suitable for electrolyzers with a high current density which may reach up to 8kA/m2.
3. The cathode shows excellent resistance to iron ion, and it can also resist some degree of polarity reversal.
