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.

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
