A research team led by Professor Jong Sung Yu of the Department of Energy Science and Engineering at DGIST has developed a new alloy structure that can significantly enhance the performance of electrode catalysts, a key component of hydrogen fuel cells.
This study enhanced the oxygen reduction reaction (ORR) at the cathode, a key factor in fuel cell efficiency, and is expected to contribute to the development of next-generation eco-friendly energy technologies.
The findings are published in Advanced Materials.
Hydrogen fuel cells are gaining attention as an eco-friendly technology that emits only water in the process of generating electricity. However, platinum (Pt), a precious metal, is primarily used as the catalyst required to improve performance and durability. As a result, efficiency enhancement and cost reduction have remained major research challenges.
