Anion Exchange Membrane Water Electrolyzers: An Overview

• The green-H-2 production through water electrolysis from renewable energies is vital in the context of developing a sustainable and cost-effective methodology. Anion exchange membrane water electrolyzer (AEMWE) is considered as a promising energy conversion device, which can be an alternative to fossil fuel-based energyplatforms. AEMWE can employ inexpensive nonprecious metal catalysts and current collectors, which is preferable forpractical applications of this technology. Membrane electrode assemblies (MEAs) for AEMWE plays a significant role forthe hydrogen production efficiency. Thus, understanding the MEA components, operation, and performance is critical forthe development of prominent materials for the AEMWE. In this review, we highlight the performances of the MEAs andtheir components, such as the AEMs and catalysts with a broad discussion of the progress with current status. Additionally,we also have put forward our assessment to lead the way for future research, to commercialize AEMWE as a provenalternative for the cost-effective production of high-purity hydrogen.
