Enhanced Electrocatalytic and Cathode‐Electrolyte Interfacial Properties With a Pr‐Based Simple Perovskite/Ruddlesden‐Popper Nanocomposite Cathode in Protonic Ceramic Fuel Cells

Small, Volume 22, Issue 13, 3 March 2026.
A novel Pr‐based nanocomposite cathode consisting of PrNi0.7Co0.3O3‐δ (simple perovskite) and Pr4Ni3O10+δ (Ruddlesden‐Popper) demonstrates enhanced oxygen absorption/surface diffusion and oxygen reduction reaction activity than pure PrNi0.7Co0.3O3‐δ. Combined with the precursor‐based cathode layer deposition technique, the nanocomposite cathode also ...
