AEM water electrolysis cell is a new type of electrolytic cell. Compared with the traditional proton exchange membrane (PEM) electrolysis technology, AEM electrolysis has the advantage of using non-precious metal catalyst and reducing material cost. In addition, the AEM technology does not require the use of concentrated lye during operation, reducing the use of corrosive chemicals, which further reduces the complexity and operating costs of the system, so that the AEM hydrogen production cell has higher efficiency, lower energy consumption and longer service life. In addition, AEM hydrogen production cell also has good safety and environmental performance, can be widely used in industrial production, energy storage and other fields.

AEM water electrolyzer is mainly composed of anion exchange membranes (AEMs), catalyst layer (CL) and gas diffusion layer (gas diffusion layer). GDL) and bipolar plate (BP) and other seal combination.

Working principle: Similar to other electrolytic water hydrogen production principles, it involves two half reactions: oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). Using pure water or low-concentration alkaline solution as the electrolyte, generally driven by 1.8 ~ 2.5V voltage, the electrolytic device breaks down water in an electrochemical manner and produces oxygen and hydrogen. Key to the technology is the anion exchange membrane, which transfers OH− from the cathode to the anode while blocking the direct transfer of gases and electrons between the electrodes.

Tankii AEM electrolyzer has the following advantages:

Cost advantage: AEM electrolyzers can use non-precious metal catalysts and titanium-free components, reducing material costs.

High current density: AEM electrolyzer can operate at high current density, which improves electrolytic efficiency.

Flexibility: AEM electrolyzer has greater flexibility in structural design and catalyst selection, and can adapt to a variety of new catalysts.

Non-acidic environment: The AEM electrolyzer operates in an alkaline environment, reducing the corrosion of the material and extending the life of the equipment.

Fast response speed: AEM electrolyzer is excellent in wave response speed and is suitable for the wave power supply of renewable energy.
