[Contact us](mailto:contact@jenabatteries.de) - ### What is an AEM system? An Anion Exchange Membrane (AEM) system is a complete hydrogen production solution based on anion exchange membrane technology. At its core, a **semipermeable AEM** selectively allows negatively charged ions (OH⁻) to pass while blocking cations and gases. This membrane is used in an **AEM electrolyzer stack**, the central electrochemical unit that splits water (H₂O) into hydrogen (H₂) and oxygen (O₂) using electricity. The stack contains multiple cells with electrodes, catalysts (often non-precious metals), and bipolar plates, with hydroxide ions moving from cathode to anode. An **AEM complete system** integrates the electrolyzer stack with a power unit and all necessary auxiliaries (water treatment, gas/liquid separation, cooling, controls, safety systems, and sometimes internal hydrogen processing) into a containerized solution. It is designed for rapid deployment and simplified operation – simply connect power, water, and hydrogen outlet to start production. - ### What are the main advantages of an AEM electrolyzer? 1. **Use of non-precious metal catalysts (nickel, iron) in an alkaline environment →** significantly lower hydrogen production costs 2. **Supports a wide temperature range and dynamic load response →** ideal for fluctuating renewable energy sources 3. **No complex gas separation systems required →** high safety 4. **High current density potential →** with optimized membrane electrodes, nearly at PEM level - ### What are the applications of the AEM electrolyzer? **1. Industrial hydrogen production –** chemical synthesis, steel industry **2. Renewable energy storage –** hydrogen from wind and solar energy for grid stabilization **3. Decentralized energy supply –** hydrogen fuel cell combined heat and power (CHP) systems **4. Transport sector –** hydrogen refueling stations for fuel cell vehicles       - ### When can the systems be delivered? We are actively seeking pilot projects and can discuss delivery timelines based on project scope and customization requirements. Typical lead times depend on system size and specific configurations, but we strive for rapid deployment to get your hydrogen production up and running as quickly as possible. ![Logo_JFB_Final_Bildmarke_02_Zeichenfläche 1-1](https://www.jenaflowbatteries.de/hs-fs/hubfs/Logo_JFB_Final_Bildmarke_02_Zeichenfl%C3%A4che%201-1.png?width=869&height=426&name=Logo_JFB_Final_Bildmarke_02_Zeichenfl%C3%A4che%201-1.png) **Jena Flow Batteries GmbH** Otto-Schott-Strasse 15 07745 Jena Germany - [T: +49 3641 8793520](tel:+49%203641%208793520) - [contact@jenabatteries.de](mailto:contact@jenabatteries.de) - - - [Impressum](https://www.jenaflowbatteries.de/impressum?hsLang=en) - [Datenschutz](https://www.jenaflowbatteries.de/datenschutz?hsLang=en) - [AEB](https://www.jenaflowbatteries.de/aeb?hsLang=en)
