Which outcome results when a solid-oxide fuel cell's (SOFC) operating temperature significantly drops with a constant fuel supply?

💡 Explanation

When SOFC temperature drops, the Arrhenius relationship dictates that the reaction rate decreases because the activation energy barrier becomes relatively larger, reducing catalytic activity at the electrodes. Therefore decreased activity results, rather than CO production increases, electrolyte fracture, or enhanced conductivity which need higher internal energy.
