The recommended alkaline electrolyte range for this product is 0.1 to 1.0 Molar. There is no mechanical reinforcement in this AEM and such membrane products are also known as self-supporting or unreinforced membranes. Because of the proprietary and advanced polymer structure, Hydroion membranes can withstand harsh operation conditions with best-in-class performance.
