The Korea Institute of Science and Technology (KIST) recently revealed a breakthrough in green hydrogen production with the development of a cost-effective catalyst. The catalyst, created by senior researchers at the Jinyoung Kim Hydrogen Fuel Cell Research Group, addresses the high cost associated with catalysts, which typically represent 40% of green hydrogen production expenses due to the use of expensive materials like iridium. By significantly reducing iridium usage by 1/20, the newly developed catalyst demonstrated a fourfold increase in water electrolysis efficiency compared to conventional options. It also showcased exceptional durability, with minimal performance degradation of less than 5% over a 100-hour evaluation period, surpassing the longevity of existing catalysts. Moreover, the catalyst's nanoporous structure not only enhanced the speed of hydrogen and oxygen movement but also set the stage for potential commercialization following additional research efforts by the team.
