, 2007 Bipolar electrochemistry is a technique that involves two opposite chemical processes, namely an oxidation and a reduction, occurring simultaneously on the surface of a conducting object, usually without connection to a power supply. The basic phenomenon has already been described and used for many decades but regained a lot of interest in recent years,

Evaluating Bicarbonate Electrolyzer Configurations for Energy‐Efficient Formate Production
Advanced Sustainable Systems, EarlyView.Reactive carbon capture (RCC) with bicarbonate electrolyzers (BEs) offers an efficient alternative to gas‐fed CO2 electrolyzers by eliminating regeneration and pressurization steps. This study optimizes BE configurations and compares RCC chains to gas‐fed carbon chains for formate production.
