Researchers have designed a self-rebuilding high-entropy electrode that transforms its surface into an active oxyhydroxide under OER conditions, sustaining high currents in AEM electrolyzers and advancing durable green hydrogen production.
Researchers at the Chinese Academy of Sciences have made a significant leap in the world of green hydrogen production. They’ve developed a self-rebuilding high-entropy antiperovskite oxygen-evolution electrode crafted on porous nickel foam. This innovative electrode can maintain industrially relevant current densities in anion exchange membrane (AEM) electrolyzers for hundreds of hours with just minor performance dips. What sets this apart is how it intentionally uses surface reconstruction instead of merely trying to prevent it, changing the game for hydrogen production.
The project is spearheaded by Guowen Meng and Bin Chen at the Institute of Solid State Physics in Hefei, and their…
