Beschreibung
Zusammenfassung:	ELECTROLYZER AND MEMBRANES An electrochemical device converts C02 into various products such as CO, HCO-, H2CO, (HCO2 )-, H2CO2 , CH30H, CH4 , C2H 4, 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 C02 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.
