Development of high-activity water electrolysis catalyst for high-efficiency alkaline fuel cell

Professor Seong Chan Jun's research team in the department of mechanical engineering has developed a robust catalyst with high activity and high efficiency for efficient water electrolysis. A very active electrocatalyst similar to Pt/RuO2 is required for application to commercial high-efficiency alkaline fuel cells, but there is still a limitation in that it is difficult to synthesize. This research team overcame this limitation by using N-doped noble metal iridium diphosphide (N-IrP2 @CC) to achieve higher water decomposition current density than conventional catalysts. The results of this study were confirmed for publication this December in 'Applied Catalysis B: Environmental' (Impact Factor: 24.319, within the top 2%, Volume 319), an international excellent journal.
