Electrolysis is a method of manufacturing products by using the principle of electrochemistry to provide electrical energy to the electrodes of the device. In the electrolysis device, since the electrode itself exotherms, the temperature of the electrode itself and the electrolyte is increased, so that the effect of electrolysis is reduced, so that the product produced by electrolysis is reduced, and even more, the electrode is more likely to be caused by temperature change during electrolysis. The aging causes the equipment life to be reduced, resulting in additional production costs. Therefore, in the past, some designs designed a water-cooling tank next to the cathode plate that generates heat during the electrolysis reaction, and the cathode plate is lowered by the contact between the tank and the cathode plate.
