Single-crystalline epitaxial thin films of PrBaCo₂O_5.5+δ (PrBCO) were prepared, and their resistance R(t) under a switching flow of oxidizing and reducing gases were measured as a function of the gas flow time t in the temperature range of 200–800 °C. During the oxidation cycle under O₂, the PrBCO films exhibit fast oscillations in their dR(t)/dt vs. t plots, which reflect the oxidation processes, Co²⁺/Co³⁺ → Co³⁺ and Co³⁺ → Co³⁺/Co⁴⁺, that the Co atoms of PrBCO undergo. Each oscillation consists of two peaks, with larger and smaller peaks representing the oxygen/hydrogen diffusion through the (BaO)(CoO₂)(PrO)(CoO₂) layers of PrBCO via the oxygen-vacancy-exchange mechanism. Furthermore, this finding paves a significant avenue for cathode materials operating in low-temperature solid-oxide-fuel-cell devices and for chemical sensors with wide range of operating temperature.
