A simple model is developed to describe the backspillover of ionic species at the solid/gas interphase as observed in NEMCA systems. This model predicts a linear relationship between work function changes and changes in the potential difference at the metal/solid electrolyte interphase, as observed experimentally. It also predicts a linear dependence of the surface coverage by ionic species on the potential difference at the metal/solid electrolyte interphase, and a linear dependence of the binding energy of adsorbed species on the work function of the gas-exposed catalyst surface.
