Core Viewpoint - The article discusses the significance of anion exchange membranes (AEM) in the hydrogen production industry, highlighting key manufacturers and their product specifications, as well as upcoming industry events related to green hydrogen technology [3][5][6]. Group 1: Anion Exchange Membrane Overview - Anion exchange membranes are critical components of AEM electrolyzer systems, requiring excellent mechanical properties, low dimensional expansion, high conductivity, and outstanding chemical stability [3]. - Major overseas manufacturers of AEMs are located in the Asia-Pacific and North America, including companies like FuMa-Tech, Dioxide Materials, Versogen, and others [3]. Group 2: Performance Summary of AEMs - A summary table lists various AEM products, their thickness, ion exchange capacity, ionic conductivity, surface resistance, tensile strength, elongation at break, and water absorption rates [5]. - For example, FuMa-Tech's Fumasep FAA3-50 has a thickness of 45-55 micrometers, an ion exchange capacity of 1.6-2.0 meq/g, and a water absorption rate of 10-25% at 25°C [5]. Group 3: Industry Developments - Evonik announced plans to build a pilot production facility in Marl, Germany, for its DURAION® AEM, expected to be operational by the end of 2025, with an annual production capacity sufficient for 2.5 GW of hydrogen electrolyzer demand [5]. - NovaMea, established in 2023, focuses on advanced AEM and catalyst development, with its first production line in Suzhou expected to be operational by April 2025 [6]. - Greenlyzer, founded by a team from Dioxide Materials, aims to develop low-cost green hydrogen production technologies, with plans to launch a megawatt-level AEM electrolyzer product by 2025 [6].
