This technology integrates non-noble metal catalysts with AEMWE system to enable high-efficiency, low-cost green hydrogen production. Featuring long-term durability and solar integration, it supports decentralized and off-grid hydrogen generation. A 3-stack AEMWE stack achieves high energy efficiency, stable operation, and H2 purity up to 99%, demonstrating strong potential for net-zero energy solutions.

This research presents a cost-effective AEMWE system with novel, high-performance catalysts. A high-entropy LDH was developed for OER and a defect-engineered, carbon-coated NiMoFe/MoO₂ for HER. These non-precious catalysts surpass IrO₂ and Pt/C in activity and stability. The AEMWE modules, including multilayer stacks, match commercial systems (e.g., Enapter), featuring low power use, high purity, and excellent durability.

This technology enables scalable, low-cost green hydrogen production via AEMWE systems using non-noble metal catalysts. It delivers high efficiency, long-term durability, and low energy consumption, meeting the EU 2030 targets. Its industrial applicability lies in its ability to decarbonize heavy industries, provide flexible energy storage for renewable grids, and enable new clean energy applications, making it a critical technology for achieving global carbon neutrality goals.
