Hydrogen production from water electrolysis is a more convenient method for producing hydrogen. In the electrolytic cell filled with electrolyte through direct current, water molecules in the electrode electrochemical reaction, decomposition into hydrogen and oxygen. When direct current is passed through some aqueous electrolyte solutions, the decomposed substances have nothing to do with the original electrolyte. What is decomposed is water as a solvent, and the original electrolyte remains in the water.

When direct current is passed through some aqueous electrolyte solutions, the decomposed substances have nothing to do with the original electrolyte. What is decomposed is water as a solvent, and the original electrolyte remains in the water.

 

For example, sulfuric acid, sodium hydroxide, potassium hydroxide, etc. belong to this type of electrolyte. In the electrolysis of water, because the degree of ionization of pure water is very small, low conductivity, is a typical weak electrolyte, so it is necessary to add the electrolyte, in order to increase the conductivity of the solution, so that the water can be smoothly electrolyzed into hydrogen and oxygen.

 

The solid polymer electrolyte, SPE electrolyzed water, was originally used to supply oxygen to spacecraft or submarines, or as a hydrogen generator in the laboratory (which can be used for gas chromatography). After the large-scale development of nuclear power, people use SPE technology to electrolyze water to produce hydrogen at the bottom of power consumption, and use SPE hydrogen-oxygen fuel cell to supply power to the outside at the peak of power supply, making it an energy storage conversion device.

 

Electrolytic pure water by direct electrolysis of pure water to produce high purity hydrogen (without alkali), electrolytic cell only electrolytic pure water can produce hydrogen. After electrification, the cathode of the electrolytic cell produces hydrogen, the anode produces oxygen, and the hydrogen enters the hydrogen/water separator. Oxygen is vented into the atmosphere. The hydrogen/water separator separates hydrogen from water. After hydrogen enters the dryer for dehumidification, it is adjusted to the rated pressure (0.02 ~ 0.45Mpa adjustable) by the pressure stabilizing valve and regulating valve and output from the outlet.
