Surface coating accelerates cathode development for next-generation anion exchange membrane water electrolysis

The conversion and storage of sustainable energy is essential in addressing the global energy and environmental crises. Hydrogen, a clean and abundant energy carrier, plays a pivotal role in decarbonizing energy sectors. Anion exchange membrane water electrolysis (AEMWE) has gained attention due to cost-effective membranes and non-precious-metal electrocatalysts at the anode. However, a significant challenge remains in the hydrogen evolution reaction (HER) under alkaline conditions, as it has significantly lower activity compared to acidic environments.
