N2 - Layered Ruddlesden–Popper oxides such as Pr2NiO4+δ are emerging as promising cathode materials without cobalt and strontium for solid oxide fuel cells. Their high oxygen mobility and mixed ionic-electronic conductivity are due to the presence of interstitial oxygen in the rock salt layers. In this study, a new experimental approach was used to combine the techniques of quasi-equilibrium oxygen release (QEOR) and oxygen partial pressure reduction (OPPR). This integrated methodology allowed accurate determination of the equilibrium exchange rate of oxygen (Ro) and the chemical diffusion coefficient (Dchem). Arrhenius analysis confirmed thermally activated oxygen transport, while the Brønsted–Evans–Polanyi (BEP) linear free energy relationship revealed mechanistic coupling between kinetics and defect thermodynamics.
