Researchers at ANEMEL have successfully developed a catalyst for water splitting that does not rely on expensive and scarce platinum group metals (PGMs). The study, recently published in Energy & Environmental Science, introduces a high-performance PGM-free catalyst for the cathode in water electrolysis, crucial for the production of green hydrogen. While current anion exchange membrane (AEM) water electrolyzers utilize PGMs at the cathode, the ANEMEL AEM electrolyzers opt for more abundant metals like nickel, aiming to make electrolyzers more cost-effective and sustainable. The researchers focused on growing a catalyst comprising nickel and molybdenum on a gas diffusion layer (GDL) using electrodeposition, a technique that allows the catalyst to be directly supported on the GDL. By choosing carbon paper as the substrate for the GDL and innovatively adjusting the electrodeposition process, they achieved a high-performing catalyst that operates stably even at high current densities. This catalyst's performance is comparable to platinum catalysts, with added stability, showcasing its potential as a top-tier non-PGM catalyst. The structural characterization of the catalyst revealed a unique surface reorganization during the reaction, with molybdenum atoms migrating to the surface and contributing to the water-splitting process. According to the first author of the study, Ariana Serban, this achievement brings us closer to large-scale green hydrogen production. By avoiding PGMs, the catalyst not only reduces costs and improves recyclability but also enhances the competitiveness of electrolyzers in the hydrogen market.
