DURAION® anion exchange membranes and ionomers are designed to enable highly efficient alkaline water electrolysis for the production of renewable hydrogen. Combining high ionic conductivity, excellent chemical stability, and outstanding mechanical durability, DURAION® materials support long-lasting electrolyzer performance and operational reliability. Their low hydrogen crossover rates contribute to improved efficiency and safety, while Evonik's deep expertise in advanced polymers ensures the optimized balance of properties required for next-generation AEM electrolyzers and scalable green hydrogen applications.
AEM Electrolysis for Cost-Effective Green Hydrogen Production
By integrating DURAION® anion exchange membranes into AEM electrolyzers, hydrogen producers can reduce both capital and operating costs compared with conventional PEM water electrolysis and traditional alkaline electrolysis technologies. Operating under mildly alkaline conditions, AEM electrolysis enables the use of noble-metal-free catalysts and cost-effective cell components, helping to improve the economic viability of green hydrogen production. At the same time, AEM electrolyzers support higher current densities and dynamic operation, making them well suited for integration with renewable energy sources.
Backed by decades of expertise in high-performance polymers, Evonik delivers scalable and customized membrane solutions for next-generation water electrolysis systems. DURAION® technology combines advanced polymer chemistry, membrane manufacturing know-how, and industrial scalability to meet the growing demand for reliable and efficient hydrogen electrolyzer technologies.
The DURAION® portfolio includes free-standing membranes (DURAION® Membrane 101), reinforced membranes (DURAION® Membrane 201), and ionomer solutions (DURAION® Ionomer S101) for the production of catalyst-coated membranes (CCM) and catalyst-coated substrates (CCS). These solutions are designed to support high-performance anion exchange membrane electrolysis and accelerate the commercialization of sustainable hydrogen production.
