Hydrogen production water electrolysis hydrogen production from electrolysis

Hydrogen energy is recognized as the most potential energy carrier in the future due to its clean and efficient characteristics. Water electrolysis hydrogen production technology has unparalleled advantages: first, no fossil fuels are used, and no harmful gases are produced; second, the product gas purity is high, usually above 99.7%; third, the technology is mature, and the process and equipment are simple ; Fourth, high level of automation, using microcomputer control, stable and reliable operation.The water electrolysis hydrogen production technology has a history of more than a century. At present, there are alkaline water electrolysis hydrogen production, proton exchange membrane water electrolysis hydrogen production and solid oxide water electrolysis hydrogen production. Hydrogen production by electrolysis of alkaline water is the most mature and widely used at present.

Principle

A pair of electrodes submerged in the electrolyte and separated by a diaphragm to prevent gas permeation constitutes a water electrolysis cell. When a certain direct current is applied to the water electrolysis cell, the water will decompose, hydrogen will be precipitated at the cathode, and oxygen will be precipitated at the anode.Alkaline water electrolysis hydrogen production has the advantages of simple process, convenient operation, no greenhouse gases such as CO2 in the production process, and high product purity (generally up to 99% to 99.99%). It is the most widely used technology.

The energy crisis and environmental pollution have become increasingly serious, threatening the survival and development of human beings. The development of renewable energy and sustainable development have become the focus of all countries. Using electricity generated by renewable energy to electrolyze water to produce hydrogen is a mature and clean hydrogen production method, and will be the preferred choice for the development of hydrogen economy.
