The green electric intelligent hydrogen production system consists of four main parts,:namely power supply, alkaline electrolysis tank, gas-liquid separation system, and hydrogen purification system; The electrolytic cell is a pressure filtration bipolar series structure, which is the core of the hydrogen production system

System composition application:

Power supply system: Convert AC power into DC power, or convert the DC power required by the renewable energy power station into DC power, including transformers, rectifier cabinets, and control cabinets, as the power supply for the electrolytic cell. By controlling the power output, the hydrogen production load of the electrolytic cell can be adjusted.

Electrolytic cell: It is the core of the green electricity hydrogen production system, where electrical energy is converted into hydrogen energy and water is decomposed into hydrogen and oxygen. Multiple small electrolytic cells are connected in series to form a large electrolytic cell, each consisting of a positive electrode, negative electrode, and separator; The positive electrode material is nickel metal, the negative electrode material is composed of porous nickel catalysts, and the diaphragm material is modified polyphenylene sulfide material with strong alkali resistance and good hydrophilicity;

Gas liquid separation system: Its main function is to separate the generated hydrogen and oxygen from the alkaline solution, achieving the purpose of recovering the alkaline solution and preliminary treatment of the gas. Including gas-liquid separation tank, alkali liquid heat exchanger, other coolers and control systems, etc

Purification system: The purity of hydrogen gas processed from the gas-liquid separation system is 99.8-99.95%, which is not applicable in most situations and requires further purification. The purification device mainly includes a deoxygenator and a dryer, whose functions are to remove oxygen and water from the hydrogen gas. After purification, the purity of hydrogen gas can reach 99.999% or above.
