Potential response of single successive constant-current-driven electrolytic hydrogen bubbles spatially separated from the electrode [PDF]

, 2022
In gas-evolving electrolytic processes, the presence of bubbles can heavily alter the mass transport of gaseous products and can induce severe overpotential penalties at the electrode through the action of bubble coverage (hyperpolarization) and ...
