- ... Solid oxide cells operated reversibly between fuel cell and electrolysis modes are promising for energy storage with extremely high capacity. La₀.₆Sr₀.₄Co₀.₂Fe₀.₈O₃₋δ (LSCF) has become the dominant oxygen electrode material in electrolysis and reversible operation. However, LSCF has been widely reported to degrade due to Sr surface segregation. The present understanding is that the segregation rat ...
