Tailoring Structure–Property Relationships in π‐Conjugated Heterocyclic Poly(arylene alkylene) Anion‐Exchange Membranes for High‐Performance Water Electrolysis

open access: yesAdvanced Science, EarlyView.
From passive to active ion transport: π‐conjugated heterocycles reconfigure the hydration environment and microphase morphology of p‐terphenyl‐based anion‐exchange membranes, enabling fast hydroxide transport and high‐performance water electrolysis. ABSTRACT Anion‐exchange membrane water electrolysis (AEMWE) is a promising technology for sustainable ...

Studies on Exchange Equilibria of Cations between Cation-Exchange Membranes and Electrolytic Solutions

Journal of Colloid and Interface Science, 2002
The variations of the selectivity coefficient K(A)(B) between Na(+)-H(+), Na(+)-K(+), and Na(+)-Cu(2+) systems and the separation factor alpha(A)(B) between Na(+)-Cu(2+) and K(+)-Cu(2+) systems in cation-exchange membranes as functions of loading and particle size of resin have been measured. The exchange affinities of all the membranes increase as H(+)

Membrane potentials and electrolyte permeation in a cation-exchange membrane

open access: yesJournal of Membrane Science, 1999
A method has been developed which permits one to determine the electrolyte permeation velocities and the membrane system permeability from measurements of the membrane potential as a function of time. The method has been applied to a cation-exchange membrane separating two aqueous KCl solutions, at the same pressure and temperature, but of different ...
