Dynamics of the Boundary Layer in Pulsed CO Electrolysis.

Electrochemical reduction of CO poses a vast potential to contribute to a defossilized industry. Despite tremendous developments within the field, mass transport limitations, carbonate salt formation, and electrode degradation mechanisms still hamper the process performance. One promising approach to tweak CO electrolysis beyond today's limitations is pulsed electrolysis with potential cycling between an operating and a regeneration mode.
