Development of Advanced Nickelate-Based Oxygen Electrodes for Solid Oxide Cells

The present work deals with the development of lanthanide nickelate based oxygen electrodes (Ln2NiO4+δ, with Ln = Nd, La or Pr) as the oxygen electrode for both solid oxide fuel cell (SOFC) and solid oxide electrolysis (SOEC) applications. The have been widely investigated as they present high oxygen diffusion parameters, making them attractive as SOFC oxygen electrodes. However, the main drawback of these nickelate phases is their reactivity...
