Composite air electrodes enable record-high performance, durability in reversible solid oxide cells

Prof. Jun-Young Park at Sejong University, in collaboration with Prof. Sun-Ju Song (Chonnam National University) and Prof. Jeong-Woo Han (Seoul National University), have published a study in Nature Energy titled "Composite air electrodes based on BaCe0.7Zr0.1Y0.1Yb0.1O3−δ for reversible solid oxide cells" that presents a new air electrode design strategy that simultaneously achieves record-high performance and exceptional durability in reversible solid oxide cells (RSOCs), a key technology for the future hydrogen economy.
