Characterization of heterogeneous anion-exchange membrane

Journal of Membrane Science, 2001
Abstract This paper reports the studies on the properties of heterogeneous anion-exchange membranes prepared from polyvinyl chloride (PVC) as binder and anion-exchange resin powder. The effect of variation of ion-exchange resin particle size as well as the resin–binder ratio on different mechanical, electrochemical and morphological properties of the

Water permeation through anion exchange membranes

Journal of Power Sources, 2018
Abstract An understanding of water permeation through solid polymer electrolyte (SPE) membranes is crucial to offset the unbalanced water activity within SPE fuel cells. We examine water permeation through an emerging class of anion exchange membranes, hexamethyl-p-terphenyl poly (dimethylbenzimidazolium) (HMT-PMBI), and compare it against series of ...

Permselectivity and microstructure of anion exchange membranes

Journal of Colloid and Interface Science, 2008
The water content, the ion exchange capacity, the transport number of counter-ion of the AMV and AMX anion exchange membranes were determined. The two-phase model (gel phase and interstitial phase) of structure microheterogeneity was validated by means of conductivity measurements.

Preparations and characterizations of anion exchange membranes and ionomers for anion exchange membrane fuel cells

2015
Anion exchange membrane fuel cells (AEMFCs) that utilize anion exchange membranes (AEMs) as solid polymer electrolytes have been attracting increasing attention in the past few decades. AEMFCs not only exhibit enhanced reaction kinetics for both fuel oxidation and oxygen reduction, but also possess improved stability and durability of catalysts in ...

Poly(pyrrolidinium)-Based Anion Exchange Membranes and Ionomers for Anion Exchange Membrane Water Electrolyzers

ECS Meeting Abstracts
Anion exchange membranes and ionomers are a critical technology for next generation energy conversion devices such as fuel cells, water electrolyzers, and CO2 electrolyzers. However, alkaline stability and poor understanding of performance and durability limiting descriptors have limited the development of a commercial benchmark membrane and ionomer,
