Advancements in Anion Exchange Membrane Cations

ECS Transactions, 2015
Anion-exchange membrane fuel cells (AME-FCs) are of increasingly popular interest as they enable the use of non-Pt fuel cell catalysts, the primary cost limitation of proton exchange membrane fuel cells. Benzyltrimethyl ammonium (BTMA) is the standard cation that has historically been utilized as the hydroxide conductor in AEMs.

Mechanical Characterization of Anion Exchange Membranes

ECS Transactions, 2013
Alkali anion exchange membrane (AEM) fuel cells have the potential for electrochemical energy conversion using inexpensive catalyst and a variety of fuel types. Stability and transport must be improved in AEMs before these devices can be fully realized.

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.
