Abstract: The disclosure provides an ion exchange membrane with ion-conducting nanochannels formed by crosslinking chitosan molecular chains to form a unique threefold helical conformation and nanochannels that facilitate ion transport. The crosslinking promotes ion conductivity, suppresses swelling in water, inhibits fuel permeation, and enhances mechanical strength. The ion exchange membrane is stable in harsh alkaline environments. The ion exchange membrane can be used in a direct methanol fuel cell that displays an exceptional power density of 305 mW cm−2.

Abstract: An anion-conducting polymeric membrane comprises a terpolymer of styrene, vinylbenzyl-Rs and vinylbenzyl-Rx. Rs is a positively charged cyclic amine group. Rx is at least one constituent selected from the group consisting Cl, OH and a reaction product between an OH or Cl and a species other than a simple amine or a cyclic amine. The total weight of the vinylbenzyl-Rx groups is greater than 0.3% 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.
