Water Electrolysis Hydrogen Production Technology
Water Electrolysis Hydrogen Production Technology – Fuel Cell Coating – Cheersonic
There are three main water electrolysis hydrogen production processes, one is alkaline water electrolysis hydrogen production, the second is PEM water electrolysis hydrogen production, and the third is solid oxide water electrolysis hydrogen production technology (SOEC). Alkaline water electrolysis for hydrogen production mostly uses a series electrolytic cell (like a filter press) with iron as the cathode side and nickel as the anode side to electrolyze the aqueous solution of caustic potash or caustic soda. Oxygen from the anode and hydrogen from the cathode. The alkaline water electrolysis hydrogen production system is relatively simple in structure, low in cost, long in life, good in stability, and low in working temperature, and does not need to use precious metals as catalysts.
1. Hydrogen production by alkaline water electrolysis
The alkaline water electrolysis hydrogen production system is mainly composed of an electrolytic cell, a gas-liquid processor (frame), a water pump, a water-alkali tank, a control cabinet, a rectifier cabinet, a rectifier transformer and a flame arrester. electrolytic cell. A pair of electrodes immersed in the electrolyte separated by a diaphragm to prevent gas penetration constitute a water electrolysis cell. When a certain direct current is applied, the water is decomposed, hydrogen gas is released at the cathode, and oxygen gas is released at the anode.
2. Hydrogen production by PEM water electrolysis
The PEM water electrolysis hydrogen production process has the advantages of high working current density, high electrolysis efficiency, no pollution in the reaction, light equipment weight, and compact structure. With the continuous breakthrough of PEM water electrolysis technology and deep coupling with renewable energy power generation technology, it can become an ideal energy storage and conversion device for grid peak regulation.
3. Solid oxide water electrolysis hydrogen production technology (SOEC)
SOEC hydrogen production technology is still in the research and development stage.
Our company’s ultrasonic spraying equipment can be sprayed on a variety of different metal alloys, including the preparation of platinum, nickel, iridium and ruthenium-based fuel cell catalyst coatings, as well as PEMs, GDLs, DMFCs (direct methanol fuel cells) and SOFCs (solid Oxide fuel cell) manufacturing. The battery manufactured by this technology has the characteristics of high battery load and high battery efficiency.
