Which outcome occurs within a solid-oxide fuel cell electrolyte when operating below the minimum operating temperature?

💡 Explanation

When a solid-oxide fuel cell operates below its minimum temperature, the ionic conductivity of the ceramic electrolyte decreases due to reduced thermal energy for ion transport, limiting oxygen ion movement. Therefore decreased ionic conductivity results, rather than increased electronic conductivity, delamination, or fuel crossover, each requiring distinct driving conditions.
