Analysis of transport phenomena in yttrium-doped zirconia in an oxygen chemical potential gradient and in short-circuit condition - Reply to the discussion from G. Petot-Ervas and C. Petot
It is shown that the essential issue in the controversy related to the nature of the driving force in the case of yttrium-doped zirconia placed between short-circuited reversible electrodes exposed to different chemical potentials is the omission of the potential drop occurring at the metal/solid electrolyte interface due to charges at the interface.
