· Ba2 Y1 Ni3 O7

Ba₂Y₁Ni₃O₇ is a mixed-valence oxide ceramic compound combining barium, yttrium, and nickel in a perovskite-related crystal structure. This material is primarily of research interest for electrochemical and energy storage applications, particularly in solid-state fuel cells and electrolyzers where its ionic conductivity and thermal stability are potentially valuable. It represents an experimental composition within the broader family of rare-earth doped nickelates, which are being investigated as alternatives to conventional yttria-stabilized zirconia (YSZ) electrolytes for intermediate-temperature solid oxide fuel cell (IT-SOFC) systems.
