Oscillatory behavior with time.
(a) OCV oscillation under a methane-to-oxygen atmosphere ratio (CH4/O2) of 2, which is the stoichiometric condition for the partial oxidation of methane. (b) Equilibrium oxygen partial pressure oscillation at the anode calculated from the Nernst equation. (c) The oscillation of impedance as a function of time. (d) Inset image shows the detailed variation of the impedance at the initial stage in the metallic regime.
