Which outcome results when excessive current passes through a solid ionic conductor such as a ceramic oxygen membrane?

💡 Explanation

Electrochemical doping occurs because **ion transport** leads to compositional changes. Excessive current will asymmetrically alter the stoichiometry at the electrode interfaces. Therefore electrochemical doping causes breakdown of the solid solution, rather than maintaining stoichiometry or reaching ideal transference numbers.
