Redox Stable Electrode Material of Symmetrical Solid Oxide Fuel Cells

Solid oxide fuel cells (SOFCs) technologies are considered the most efficient and environmentally-friendly option for both stationary distributed power generation due to their advantages of low pollution, noise strong building blocks. Despite potential, widespread adoption SOFC technology has not yet been achieved. The main reason is that high cost manufacturing maintenance insufficient operating life make less competitive economically. More more people begin pay attention symmetrical solid (SSOFCs) because SSOFCs have many potential advantages, such as improving thermal mechanical compatibility between electrolyte electrode, reducing costs, ability resist coking sulfur poisoning. This article reviews development redox stable electrodes in recent years, summarizes current research hotspots, looks forward future electrode materials.
