LG Chem Develops PEM Water Electrolysis Electrode With Reduced Rare Metal
LG Chem has developed a new electrode technology for PEM water electrolysis that significantly reduces the amount of iridium required. This innovation improves the durability and commercial viability of green hydrogen production.
Why it matters
Reducing reliance on rare metals is critical for scaling green hydrogen as a sustainable energy source.
LG Chem has developed a proton exchange membrane (PEM) water electrolysis electrode technology that reduces the use of the rare metal iridium (Ir) by more than half while improving durability. It also verified large-area electrode production, raising the commercialization potential of this next-generation green hydrogen production material.
LG Chem said on July 26 that a research team at the Platform Technology Research Center under its CTO organization developed an interface stabilization technology that improves the performance and durability of PEM water electrolysis electrodes. The research results were published in the international journal Nature Communications on July 21.
