国内20家AEM膜布局企业及产品一览

Core Viewpoint - The article discusses the advancements and developments in Anion Exchange Membrane (AEM) technology, highlighting the performance parameters of various companies' AEM products and their contributions to the hydrogen production industry [3][5][7]. Summary by Sections AEM Technology Overview - AEM is a critical component in the third-generation water electrolysis hydrogen production technology, facilitating the conduction of OH- ions and preventing the mixing of hydrogen and oxygen gases [3]. - The performance of AEM directly impacts the efficiency, stability, and lifespan of electrolysis cells [3]. Composition and Performance Factors - AEM consists of a polymer backbone, cationic groups, and freely moving anions, with the polymer backbone determining mechanical strength and thermal stability [3][4]. - Common polymer backbones include polybenzimidazole and polyether ether ketone, while quaternary ammonium and imidazolium groups are prevalent cationic groups [3][4]. Industry Landscape - Companies focusing on AEM membranes can be categorized into two groups: those specializing in membrane materials and those producing AEM electrolysis cells [4][5]. - Notable companies in the membrane production sector include Han Cheng Technology, Dongyue Group, and Jia Membrane Technology, while AEM electrolysis cell manufacturers include Yiwei Hydrogen Energy and Qingneng Co., Ltd. [4][5]. Performance Parameters of AEM Products - A summary table presents the performance parameters of various AEM products from different companies, including thickness, ion exchange capacity, ionic conductivity, tensile strength, and alkaline stability [5][6]. - For instance, Jia Membrane Technology's KMem®AM 01-20 has a thickness of 20±2 μm and an ionic conductivity of 125±5 mS/cm at 60°C [5]. Recent Developments - Jia Membrane Technology announced the commissioning of its first AEM production line with an annual capacity of 60,000 m² [7]. - Limo Technology has developed a fourth-generation AEM using quinine ring ketone and aromatic compounds, with a production line established in Xuzhou [7]. - Qingshui Membrane Technology's CWay-01 series has achieved performance metrics that meet global standards, with a new production line expected to be operational soon [7]. - Zhiqing Materials has developed a range of AEM products with thicknesses from 20 to 100 μm and has secured orders from leading electrolysis cell manufacturers [8]. - Yiwei Hydrogen Energy has upgraded its membrane materials, resulting in a significant reduction in cell pressure under specific current densities [8]. Conclusion - The advancements in AEM technology and the competitive landscape among various companies indicate a growing focus on improving hydrogen production efficiency and sustainability [7][8].
