Precautions for use:
1. Pay attention to protecting the surface of the coating, and strictly prevent scratches, collisions, and abrasions during transportation, installation, and use. The impact of oil, strong corrosive substances, and deformation on the titanium electrode should be prevented.
2. To prevent the short circuit of the cathode and anode plates, do not arrange the electrodes in the opposite direction.
3. Operate in strict accordance with the process specifications. Excessive current, high voltage, sudden power failure, high solution concentration, temperature, impurity ions and other factors will affect the use effect of the coated titanium electrode.
1. The principle of hydrogen production by electrolysis of water
The water electrolysis technology is relatively mature in my country, and the electrolysis hydrogen production equipment is simple. The obtained H2 has high purity and low impurity content. It is suitable for various occasions. The key to water electrolysis hydrogen production is how to reduce the energy consumption in the electrolysis process and improve the energy conversion efficiency. Hydrogen production by electrolysis of water generally uses strong alkali, strong acid or oxygen-containing salt solution as the electrolyte. Commonly used is the electrolysis method, and the electrolytic cell is the reaction place. The water splitting reaction is carried out in an electrolytic cell. The electrolytic cell is filled with electrolyte. The electrolytic cell is divided into an anode chamber and a cathode chamber by a diaphragm, and electrodes are placed in each chamber. Since the conductivity of water is very small, an aqueous solution with an electrolyte is used. When a current passes between the electrodes under a certain voltage, H2 is generated on the cathode and O2 is generated on the anode.
2. Selection of titanium anode for hydrogen production by electrolysis of water
The core part of the water electrolysis hydrogen production equipment is the electrolytic cell, and the anode material is the key core part of the electrolytic cell. The choice of anode material largely determines the cell voltage and energy consumption of water electrolysis, and directly affects the cost. Each reaction chamber of the electrolytic cell is composed of an anode plate, an anode and an auxiliary grid, a diaphragm, a gasket, a cathode and an auxiliary grid, and a cathode plate. In the electrolytic cell, each plate is both an anode and a cathode, the middle plate is the anode, the left and right end plates are the cathode, the side of the plate facing the middle plate is the cathode, and the other side is the anode.
The anodes are platinum-plated anodes or noble metal oxide anodes, but the cost of platinum-plated anodes is relatively high, and the use of noble metal oxide anodes is more cost-effective. In precious metal oxides, RuO2 and IRO2 both have good oxygen evolution catalytic activity and low peroxygen potential. They are prepared by superheated oxidation and are firmly bonded to the substrate in the form of oxides. The substrate uses industrial pure titanium, and the base layer is used. After deactivation, titanium has good corrosion resistance and can be used repeatedly as a base material. In the long run, it saves costs, but which one is more suitable depends on the actual working conditions and cost budget.
