Science

Within a solid-oxide fuel cell lacking sufficient water vapor at the anode, which consequence results from local charge imbalance?

A)Formation of performance-degrading BaO
B)Increased hydrogen oxidation resistance
C)Enhanced oxygen ion diffusion rate
D)Suppressed metallic nickel cluster formation

💡 Explanation

Formation of BaO can reduce the electrochemically active surface area because depletion of water vapor inhibits proton formation, limiting ionic conductivity; therefore, barium oxide forms rather than stable hydroxide species, underperforming standard conditions.
