On September 8, a team of researchers, led by Prof. Guntae Kim (School of Energy and Chemical Engineering) and Prof. Noe Jung Park (School of Natural Science) has announced that they have invented a highly active and durable electrode material for commercialized Solid-Oxide Fuel Cell (SOFC) that will provide improved SOFC performance.
This study is a collaboration amongst ten scientists from International Institute for Carbon Neutral Energy Research at Kyushu University, Dong-Eui University, and Center for Multidimensional Carbon Materials at UNIST.
This class of double-perovskite compounds display fast oxygen ion diffusion and high catalytic activity toward oxygen reduction while maintain excellent compatibility with the electrolyte. According to Prof. Kim, this has not only increased the stability of the existing electrode but also increased the performance of SOFC by diffusing the oxygen ion more rapidly.
This scientific research regarding SOFC appeared in the September 8, 2014 issue of Angewandte Chemie International Edition, one of the prime chemistry journals in the world with an Impact Factor higher than those of comparable journals.
Moreover, this research was supported by the Mid-career Research Program, funded by the Korea Government Ministry of Science, ICT and Future Planning (MSIP) and the Basic Science Research Program, funded by the Ministry of Education through the National Research Foundation of Korea. It was also supported by the New & Renewable Energy of the Korea Institute of Energy Technology Evaluation and Planning, grant funded by the Korea Ministry of Knowledge Economy.
