Development of anion-exchange membrane for anion-exchange membrane fuel cells
Materials Research Innovations, 2015Anion-exchange membrane fuel cells possess several important advantages, and have attracted a lot of attention. In this paper, the characteristic of different type anion-exchange membrane were introduced. In view of the ion conductivity and stability of anion-exchange membrane, these anion-exchange membranes based on polybenzimidazole ...

Contamination of an anion-exchange membrane by glutathione
Bioseparation, 2000Electrodialysis, which can separate electrolytes under mild conditions by using ion-exchange membranes, is a strong candidate for separation of GSH from yeast extracts, because GSH is unstable and easily oxidized forming a disulfide bond especially under alkali conditions. In this paper, sorption behavior of GSH on an anion-exchange membrane, in the pH

Permselectivity and microstructure of anion exchange membranes
Journal of Colloid and Interface Science, 2008The 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.

Microheterogeneity of anion exchange membranes
Journal of Applied Polymer Science, 1975Anion exchange membranes (ferricyanide ion type) prepared by the “paste method” were treated with an aqueous solution of hydrogen peroxide, and the resultant microporous membranes had no ion exchange capacity but water permeability. By measuring the water permeability of the membranes and observing the electron microphotographs of the membrane surfaces,

3D Printing of Micropatterned Anion Exchange Membranes
ACS Applied Materials & Interfaces, 2016Micropatterned anion exchange membranes (AEMs) have been 3D printed via a photoinitiated free radical polymerization and quaternization process. The photocurable formulation, consisting of diurethane dimethacrylate (DUDA), poly(ethylene glycol) diacrylate (PEGDA), dipentaerythritol penta-/hexa- acrylate, and 4-vinylbenzyl chloride (VBC), was directly ...

Hydroxide Solvation and Transport in Anion Exchange Membranes
Journal of the American Chemical Society, 2016Understanding hydroxide solvation and transport in anion exchange membranes (AEMs) can provide important insight into the design principles of these new membranes. To accurately model hydroxide solvation and transport, we developed a new multiscale reactive molecular dynamics model for hydroxide in aqueous solution, which was then subsequently modified

Metal-Cation-Based Anion Exchange Membranes
Journal of the American Chemical Society, 2012Here we present the first metal-cation-based anion exchange membranes (AEMs), which were synthesized by copolymerization and cross-linking of a norbornene monomer functionalized with a water-soluble bis(terpyridine)ruthenium(II) complex and dicyclopentadiene. Each ruthenium complex has two associated counteranions, unlike most ammonium- and phosphonium-

(Invited) Anion Exchange Membranes
ECS Meeting Abstracts, 2019I didn't think I was going to work on anion exchange membranes until Shimshon gave me a call in early 2008 wanting to talk about quaternary ammonium-containing polymers. It has been an interesting journey since then. CellEra's support allowed me to hire my first postdoc - Jingling Yan - and also introduced me to a great cast of characters including ...

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 ...
