Electrolytic Bubble Coalescence on Hydrophobic Cavity Arrays Determines Departure Radius and Lowers Electrolyte Supersaturation

Small, EarlyView.
Bubble evolution is a key source of inefficiency in electrolyzers. In this study, custom‐fabricated electrodes with arrays of preferential nucleation sites are used to overcome the spatial randomness of bubble nucleation. Bubble departure size is shown to strongly depend on coalescence.
