- Facilitating the hydrogen economy through highly active and efficient nickel-based alloy catalysts
- Facilitating the hydrogen economy through highly active and efficient nickel-based alloy catalysts To promote the transition to an eco-friendly hydrogen economy, Professor Jongsup Hong's team in the Department of Mechanical Engineering developed a nickel-based alloy catalyst that can be used for the anode of hydrogen fuel cells. Through this study, it was possible to operate fuel cell power generation while producing hydrogen inside a low-temperature hydrogen fuel cell by directly injecting city gas (methane) without a hydrogen generator. This study was published as an inside-front-cover in the Journal of Materials Chemistry A (IF: 11.301) and was selected as the journal's HOT Paper. In recognition of the excellence of research results, this study was announced publicly by the Korea Research Foundation and various online articles on March 25 to promote the research results to the media.
