When direct current is applied to some electrolyte solutions, the dissolved components are irrelevant to the original electrolyte. Dissolved water serves as an organic solvent, leaving the original electrolyte in the water. For example, hydrochloric acid, sodium hydroxide solutions, and ferric chloride solutions are such electrolytes.

Water electrolysis hydrogen production water electrolysis, pure water is a very typical weak electrolyte, due to low ionization degree, low conductivity. Therefore, these electrolytes must be added to improve the conductivity of the saturated solution so that water can be electrolyzed successfully into hydrogen and oxygen.

Solid polymer electrolyte, SPE for water electrolysis, originally used for O2 in space shuttles or submarines, or as a hydrogen generator in laboratories (available as a weather chromatograph). After the scale development trend of nuclear power plants, we use SPE technology to electrolyze water to produce hydrogen in the low power consumption period, and use SPE hydrogen and oxygen fuel cells in the peak distribution period to become energy storage technology conversion equipment.

In recent years, the development trend of renewable energy electrolysis of water to produce hydrogen in today's world is fast. Many Of our country has already gradually set up hydrogen energy in the development planning of industrial production, engineering construction, power engineering and other fields outside the transportation industry, and has performed well in the overall planning and demonstration application of government departments. In this paper, the specific research and future prospects of the production of green hydrogen electrolytic water hydrogen technology,

Generally speaking, hydrogen production by electrolysis of water using renewable energy is characterized by efficient digestion and absorption of waste wind power generation and light concentration, reducing the cost of hydrogen production; The efficiency of energy conversion from electricity to hydrogen is relatively high (60%~80%). Using renewable energy to generate electricity electrolysis of water to produce hydrogen is a low-carbon environmental protection process. The imbalance of green energy development trend is increasingly prominent, especially the green energy transaction problem, which seriously restricts the sustainable development concept of physical and mental health of electric power enterprises.
