Which consequence arises in water electrolysis when electrode surface area decreases?

💡 Explanation

Decreasing electrode area requires higher current density to maintain similar molecule production rates, because increased local current density enhances electrode polarization. Therefore, overpotential will rise driving electrode instability, rather than changing conductivity.
