Details For high temperature electrochemical devices, the cathode reaction mechanism for electrode or electrode/electrolyte are discussed. Especially, we discuss the rate-determining-step for the he perovskite-related oxides cathode/electrolyte. We investigated in situ depth resolved X-ray absorption spectroscopy (XAS) measurement for high temperature electrochemical devices component materials under the operating condition of high temperature electrochemical devices. The in situ XAS results clearly indicated that the rate-determining step is the reaction at electrode/electrolyte interface.
