The research team of Professor She-Kyu Park (Dept. of Chemical Engineering) developed an porous catalyst electrode with excellent water electrolysis reactivity and durability for polymer electrolyte water electrolysis used in green hydrogen production through collaborative research with the research team of Professor Yong-tae Kim (POSTECH) , Dr. Su Kim at Rivian Automotives, and Dr. Shao at Pacific Northwest National lab. The research also focused on understanding the factors determining the hydrogen production efficiency during PEMWE operation and the deterioration of components over extended operation periods. The results are expected to contribute significantly to future applications in water electrolysis technology for green hydrogen production.
