The invented bio-electrical system is a housing-electrode which allows insertion of another electrode for various electrochemical and bio-electrical applications. Together with other invented elements as well as standard components, the system is fully scalable, modular, and allows production and collection of gases under pressure. It can be built in many shapes, such as the embodied tubular shape. The design allows operation on unstable ground, for example on ships. Flow of electrolyte can be regulated and directed in cascaded reactions by opening and closing the compartments of the outer or the inner electrodes using the provided electrode holders. The redox conditions inside the system can be controlled using off-the-shelf power supplies which are controlled using the provided algorithm. Gas collection can be regulated based on the level of liquid inside the system using the provided float switches or conductivity probes even as the system is moving or operated under zero-gravity conditions.

The present disclosure relates to an electrochemical flow cell that includes a gap positioned between an ion exchange membrane (IEM) and a cathode gas diffusion electrode (GDE), where the gap is positioned to contain a liquid and the gap has a thickness value, as defined by the distance between the IEM and the cathode GDE, of between greater than zero mm and less than about 2.0 mm. In some embodiments of the present disclosure, the gap may be between about 0.1 mm and about 1.0 mm.

The invention concerns a process for the electrochemical production of formate. The process is performed in an electrochemical cell comprising a cathode compartment containing a cathode, an anode compartment containing a nickel-based anode and an ion exchange membrane separating the anode compartment from the cathode compartment. The process comprises the following steps: (a) feeding an anolyte comprising at least one polyol to the anode compartment; (b) feeding a catholyte comprising CO.sub.2 to the cathode compartment; (c) and applying a voltage difference between the cathode and the anode such that at the cathode CO.sub.2 is reduced to formate and at the anode the at least one polyol is oxidized to formate.
