The proposed system has attracted much attention as a new promising option for the cost-effective and highly-efficient hydrogen production, as it shows excellent performance compared with other water-electrolysis systems.
This breakthrough has been led by Professor Guntae Kim in the School of Energy and Chemical Engineering at UNIST in collaboration with Professor Tak-Hyoung Lim of Korea Institute of Energy Research (KIER) and Professor Jeeyoung Shin of Sookmyung Women’s University.
A solid oxide electrolyzer cell (SOEC) consists of two electrodes and an electrolyte that are all in solid-state. They are strongly desired as novel candidates for the hydrogen production, as they require no need to replenish lost electrolytes, while eliminating the corrosion problems. Besides, SOECs also operate at relatively high temperatures (700-1000 °C), which helps to offer reduced electrical energy consumption.
