Evaluating Cation-Exchange Membrane Properties Affecting Polymer Electrolyte Membrane Water Electrolysis. [PDF]

ACS Omega
Ion-exchange membranes are crucial components in water electrolysis using polymer electrolyte membrane water electrolysis (PEMWE) for green hydrogen production. However, the impact of membrane properties on the device performance has not been adequately studied, and the extent to which easily implementable strategies can improve the membrane properties

Electrochemically induced precipitation enables fresh urine stabilization and facilitates source separation [PDF]

, 2020
Source separation of urine can enable nutrient recycling, facilitate wastewater management, and conserve water. Without stabilization of the urine, urea is quickly hydrolyzed into ammonia and (bi)carbonate, causing nutrient loss, clogging of collection ...

Permselectivity of Cation Exchange Membranes Modified by Polyaniline [PDF]

Membranes, 2021
This work discusses the applicability of polyaniline-modified cation exchange membranes for the separation of monovalent/divalent cations by electrodialysis. A novel method of membrane modification directly in the electrodialysis unit is used to prepare permselective membranes.

Graphene modified fluorinated cation-exchange membranes for proton exchange membrane water electrolysis [PDF]

International Journal of Hydrogen Energy, 2019
Abstract One of major current technical challenges in proton exchange membrane water electrolysis (PEMWE) is the limited proton conductivity. Nowadays, graphene is considered one of the most promising candidates for improving the ionic transport properties, isotopic selectivity and proton conductivity throughout the unique two-dimensional structure ...

Correlation between macroscopic sugar transfer and nanoscale interactions in cation exchange membranes [PDF]

, 2015
Previous experimental work has shown that the transfer of organic solutes through ion-exchange membranes depends on the membrane counter-ion and that this dependence is probably linked to the interactions taking place at the nanoscale inside the membrane
