Short circuit phenomenon of #electrolyticCell 1, what is the short circuit of the electrolytic cellA short circuit in an electrolytic cell means that a path is formed between different parts of the cell that should not otherwise be conducting, and there is a potential difference. The current does not follow the normal path through the electrolytic cell for electrolytic reaction, but through the abnormal path conduction, the abnormal current flow situation. Some of this short-circuit phenomenon occurs in the tank, but also some occur outside the tank.II. Harm of Short Circuit of ElectrolyzerDamage to the equipment.Short-circuit sometimes produces high temperature and strong arc light, causing damage to the electrolytic cell, and may even cause safety accidents such as fire or explosion. 2.Affect production efficiency. A short circuit will cause the current to fail to pass through the electrolyte to carry out the electrolytic reaction normally, thus reducing the production efficiency. The current will be lost through a short-circuit path, making hydrogen production less efficient. 3Affect the purity of the gas. A short circuit can cause the gas in the cell to mix, reducing the purity of the hydrogen. Affect the quality of product gas and application effect, if the mixture of hydrogen and oxygen to a certain proportion, it is easy to cause explosion and other safety accidents. 4.Production stability. The occurrence of short circuit phenomenon may lead to the electrolytic cell can not work properly, which will cause interference to the production plan. Enterprises need to constantly adjust their production plans to adapt to the uncertainties caused by short-circuit. III. Causes of Short Circuit of #Electrolyzer Cause of short circuit in slot body: Deposition of metal impurities.The deposition of metal impurities causes a path to be formed between two points at different potentials, causing a short circuit. The air inlet and outlet of the chamber is blocked.The liquid level in the chamber drops and the voltage between the poles rises due to the blockage of the inlet and outlet holes, which causes the breakdown between the anode and the cathode to ignite, causing a short circuit, and in severe cases, the tank body is pierced. External Short Circuit Causes:Problems after maintenance.When the power is driven after maintenance, the metal debris on the tank body is not cleaned, and some parts are unqualified due to moisture, or are not isolated with insulation pads, resulting in a short circuit.Other conditions in operation.During operation, the leakage of alkali may cause short-circuit ignition between two components which are close to each other and have different potentials; Or the large screw is charged and short-circuited due to the leakage of lye. #H2 #Hydrogen
