Abstract
Methods and systems related to oxocarbon electrolyzers are disclosed herein. A disclosed system includes an oxocarbon electrolysis reactor. The rector includes an aqueous anode area with an oxidation substrate, a gaseous cathode area with an oxocarbon species as a reduction substrate, and an electroneutral separator separating the anode area and the cathode area while allowing ionic migration between the anode area and cathode area. In specific approaches disclosed herein the electroneutral separator is a polymer having a coating, the coating is formed of an aliphatic molecule, and the coating increases a hydrophilicity of the electroneutral separator. In specific approaches disclosed herein, the electroneutral separator is a polymer having a coating, the polymer comprises aliphatic carbon chains, and the coating is an aliphatic carbon chain with one or more hydrophilic functional groups.
