Title (EN) ELECTROLYZER AND MEMBRANES
(FR) ÉLECTROLYSEUR ET MEMBRANES
Abstract:
(EN) An electrochemical device converts CO2 into various products such as CO, HCO-, H2CO, (HCO2)-, H2CO2, CH3OH, CH4, C2H4, CH3CH2OH, CH3COO-, CH3COOH, C2H6, (COOH)2, (COO-)2, H2C=CHCOOH, and CF3COOH. The device is made up of an anode, a cathode, and a Helper Membrane. In some embodiments, the device can also contain a catalytically active element. In some embodiments, the device is able to achieve a faradaic efficiency above 50% and CO2 conversion current density over 20 mA/cm2 at a cell voltage of 3.0 V. In some embodiments, the Helper Membrane comprises a polymer containing an imidazolium ligand, a pyridinium ligand, or a phosphonium ligand.
(FR) Cette invention concerne un dispositif électrochimique qui convertit le CO2 en divers produites tels que le CO, le HCO-, le H2CO, le (HCO2)-, le H2CO2, le CH3OH, le CH4, le C2H4, le CH3CH2OH, le CH3COO-, le CH3COOH, le C2H6, le (COOH)2, le (COO-)2, le H2C=CHOOH et le CF3COOH. Ledit dispositif est constitué d'une anode, d'une cathode et d'une membrane auxiliaire. Selon certains modes de réalisation, ledit dispositif comprend en outre un élément catalytique actif. Selon certains modes de réalisation, le dispositif est capable d'atteindre un rendement faradique supérieur à 50 % et une densité de courant de conversion de CO2 supérieure à 20 mA/cm2 à une tension de bain de 3,0 V. Selon certains modes de réalisation, la membrane auxiliaire comprend un polymère contenant un ligand d'imidazole, un ligand de pyridine ou un ligand de phosphonium.
