Science

Which outcome limits the electrolytic production rate when overpotential increases within a fuel cell?

A)Decreased electrode surface polarization
B)Elevated mass transport limitations
C)Enhanced charge-transfer kinetics
D)Reduced activation energy requirement

💡 Explanation

Increased overpotential enhances the reaction rate initially; however, mass transport limitations become dominant because reactants cannot reach electrode surfaces quickly enough; therefore, the production rate plateaus, rather than accelerating uncontrollably given charge kinetics.
