Abstract

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.
