China Alkaline Water Electrolyzer Stack Bipolar Electrode

What is Alkaline hydrogen electrolyzer？

Alkaline hydrogen electrolyzer is a chemical process that splits water molecules into hydrogen and oxygen gases using an alkaline electrolyte solution, typically potassium hydroxide (KOH). It involves using an electrolyzer, consisting of an anode and a cathode immersed in the electrolyte solution.

In the context of an alkaline water electrolyzer, a bipolar electrode is a conductive plate that serves multiple functions. It acts as a bridge between adjacent cells in the electrolyzer stack. It facilitates the flow of electrical current between the anode of one cell and the cathode of the adjoining cell, ensuring efficient operation of the electrolyzer stack. It aids in the even distribution of the electrolyte (alkaline solution) to the electrodes, which is crucial for the electrolysis reaction.  In a stack configuration, multiple electrolyzer cells are arranged in series. The bipolar plates are positioned between each pair of cells, alternating between acting as the anode for one cell and the cathode for the next.

Advantages of JINFAN Bipolar Electrode Plate:

• Corrosion Resistance: Since the bipolar plates are exposed to alkaline conditions and high current densities, they must resist corrosion and wear to ensure long-term reliability. JINFAN Plate uses high-grade alloys like 316L, offers good corrosion resistance and strength.
• Thermal Management: Effective thermal management through the bipolar plates helps maintain optimal operating temperatures and prevent overheating. JINFAN Plate uses Nickel alloys which are highly resistant to corrosion and have good electrical conductivity.
