Alkaline electrolyzer stack is the key part to produce hydrogen by electrolysis water.According to whether is it have separation membrane,it can be divided into pure hydrogen cell and hydrogen oxygen cell.
The alkaline water hydrogen production electrolysis cell is the “heart” of the alkaline water electrolysis hydrogen production system, which is the core equipment. The reason for saying this is because:
The performance of the alkaline electrolyzer stack is directly related to the hydrogen production efficiency of the entire hydrogen production system.
The manufacturing cost of electrolytic cells accounts for a large proportion of the entire equipment manufacturing cost, and the larger the hydrogen production per unit time of the equipment, the higher the proportion of electrolytic cells in the entire equipment manufacturing cost.

Alkali water electrolysis, as the most mature electrolysis technology, occupies a dominant position. Especially in some large-scale projects. The diaphragm of alkaline water electrolysis hydrogen production electrolysis cell is mainly composed of polymer materials, which plays a role in separating gases. The cathode and anode are mainly composed of metal alloys.
The principle is that at the cathode, water molecules are decomposed into H+and OH -. And H+generates electrons to form hydrogen atoms. Which further generate hydrogen molecules (H2). OH – passes through the porous diaphragm under the electric field force between the cathode and anode, reaches the anode. And loses electrons at the anode to generate a water molecule and an oxygen molecule.
Electrolytic hydrogen production driven by renewable energy is considered a good helper for improving global climate and energy issues. And alkaline electrolyzers are known as key equipment for large-scale hydrogen production from renewable energy. With the growing demand for green hydrogen development. Electrolytic water hydrogen production is facing a new round of development opportunities.
Besides alkaline electrolyzer cell,we also supply complete alkaline hydrogen production equipment.
