Hydrogen generation plant water electrolysis hydrogen generator h2 electrolysis

At present, there are many known ways to produce hydrogen, including hydrogen production by ammonia decomposition, hydrogen production by natural gas, hydrogen production by methanol cracking, hydrogen production by water electrolysis, etc. Among them, the most widely used method is hydrogen production by water electrolysis. Hydrogen production by lye electrolysis: This hydrogen production technology has a long history. It was first learned from the Soviet Union. It was later applied to domestic power plants, polysilicon, chemical enterprises, and small laboratory chromatography supporting gas sources. The equipment is reliable in operation and low in cost. , The purity of hydrogen is generally around 99.8%.

However, hydrogen is corrosive, and long-term operation for more than 5 years will corrode various parts. It needs major repairs every five years, and the maintenance cost is relatively high. Discarded lye needs to be treated in an environmentally friendly manner, and special personnel need to be trained to work. Special attention must be paid to the adjustment of hydrogen and oxygen.

Water electrolysis hydrogen production devices have been more and more widely used, including new energy, electric power, petrochemical, pharmaceutical, metallurgy, polysilicon, meteorology, aerospace and other fields and major gas companies. The purity of hydrogen produced by electrolysis of water can be as high as 99%, which is an important method for industrial production of hydrogen. During the electrolysis of sodium hydroxide (potassium) solution, oxygen is released from the anode and hydrogen is released from the cathode.
