A Comprehensive Analysis of the Commercialization of Anion Exchange Membranes (AEM): An In-Depth Dissection and the Current Research Progress in China

### Anion Exchange Membranes (AEM) Anion exchange membranes are core components in electrolysis of water for hydrogen production and fuel cells, responsible for conducting hydroxide ions (OH⁻) and isolating hydrogen and oxygen gases. Compared with traditional proton exchange membranes (PEM), the biggest advantage of AEM devices is that they do not require noble metal catalysts, which significantly reduces the cost of hydrogen production. They are considered a key technology for realizing the “green hydrogen economy”! With the development of anion exchange membrane water electrolysis (AEM-WE) technology in recent years, some AEMs have successfully made the transition from the laboratory to commercialization, such as Sustainion®, Aemion™, and PiperION®. Up to now, a considerable number of domestic membrane and electrolyzer companies have successively reported their advanced AEMs, but very few are circulating in the market. Concerns about membrane quality and potential chemical structure patent restrictions are probably the biggest bottlenecks limiting their further commercialization. Companies such as EVE Hydrogen, JiaMo Technology, and Jushi Hydrogen Friends, which are supported by university technologies, have also launched their AEM products. Qingneng Shares, Hancheng Technology, Future Hydrogen, Evonik, and other companies have also announced the launch of high-performance AEMs.
