Abstract
An anion-conducting polymeric membrane comprises vinylbenzyl-Rand a substituted ethene. Ris a positively charged cyclic amine group. The total weight of the vinylbenzyl-Rgroups is greater than 15% of the total weight of the membrane. In a preferred embodiment, the membrane is a Helper Membrane that increases the faradaic efficiency of an electrochemical cell into which the membrane is incorporated, and also allows product formation at lower voltages than in cells without the Helper Membrane.
