Anion Exchange Membrane Electrolyser (AEM)

Water quality significantly impacts the performance and longevity of an electrolyzer. Impurities in the water can result in the accumulation of ions and other impurites in the membrane, leading to degradation and reduced system efficiency. 

Using high-purity water, such as Type II and Type III defined by American Society for Testing and Materials (ASTM), can help mitigate these risks by minimizing the presence of contaminants that may harm the electrolyzer stack. Polymer piping systems are highly effective in preserving water purity in electrolyzers. 

Unlike metal piping systems, polymers are resistant to corrosion and do not introduce impurities into the water, ensuring that it remains free from contaminants that could affect the performance of the electrolyzer.

An anion exchange membrane (AEM) electrolyzer is a device that uses electricity to split water into hydrogen and oxygen. It works by enabling the movement of anions, particularly hydroxide ions (OH⁻), from the cathode to the anode through a special membrane, while preventing cations from passing through.

• Electrolysis Process: At the cathode (negative electrode), water molecules are reduced by electricity, producing hydrogen gas (H₂) and hydroxide ions (OH⁻). The hydroxide ions then migrate through the anion exchange membrane to the anode.
• Anode Reaction: The anode (positive electrode) oxidizes the hydroxide ions, releasing oxygen gas (O₂) and water.
