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

A)Reduced oxide ion conductivity
B)Increased electrode polarization losses
C)Enhanced fuel crossover rates
D)Catalyst poisoning within fuel cell

💡 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.
