As green hydrogen emerges as a key next-generation clean energy source, securing technologies that enable its stable and cost-effective production has become a critical challenge. However, conventional water electrolysis technologies face limitations in large-scale deployment due to high system costs and operational burdens.
KIST has developed a novel membrane material for water electrolysis that operates stably and has significantly higher conductivity under low alkalinity conditions than existing systems. The newly developed membrane maintains high hydrogen production performance even in low-concentration alkaline environments, providing a technological foundation for low-alkalinity water electrolysis.
