The location of the CO2 electroreduction reaction on catalytic layers (CLs) is a subject of debate when gas diffusion electrodes (GDEs) are used. This perspective article discusses the possible formation of narrow, thin, and long layers of precursor films of aqueous catholytes, which spread very clo...
