Theoretical V-I characteristics of the solid-oxide thermocell using the oxide ion and electronic mixed conductors

摘要

The theoretical relationships between the terminal voltage (V) and external current (I) of a solid-oxide thermocell using oxide ion-electron mixed conductors were derived based on Wagner's theory. The electrical transport parameters Of Y2Ti2O7 were used to calculate the theoretical V-I characteristics. A mixed discharge region, where the partial currents of the oxide ions and electronic carriers flow in the same direction, appeared under an air atmosphere. (C) 2002 Elsevier Science B.V.
