Which risk increases when a solid oxide fuel cell electrolyte contains contaminants?

💡 Explanation

Reduced oxide ion conductivity increases due to dopant segregation. Grain boundary blocking increases because impurities interfere with the migration of oxygen vacancies. This lowers efficiency, therefore performance degrades with oxide ion deficiency, rather than improved activity.
