BINDING AND DEGRADATION REACTION OF HYDROXIDE IONS WITH SEVERAL QUATERNARY AMMONIUM HEAD GROUPS OF ANION EXCHANGE MEMBRANES INVESTIGATED BY THE DFT METHOD

Karibayev, Mirat; Myrzakhmetov, Bauyrzhan; Kalybekkyzy, Sandugash; Wang, Yanwei; Mentbayeva, Almagul (Molecules, 2022)

Commercialization of anion exchange membrane fuel cells (AEMFCs) has been limited due to the chemical degradation of various quaternary ammonium (QA) head groups, which af fects the transportation of hydroxide (OH−) ions ...
BINDING, REACTION, AND ACTIVATION ENERGIES OF OH- IONS INTERACTING AND REACTING TO SOME HEAD GROUPS OF ANION EXCHANGE MEMBRANE EXPLORED VIA THE DFT METHOD

Karibayev, Mirat; Myrzakhmetov, Bauyrzhan; Kalybekkyzy, Sandugash; Mentbayeva, Almagul; Wang, Yanwei (National Laboratory Astana, 2022-08)

The main drawback of Anion Exchange Membranes is related to the chemical instability of cationic head groups and the transportation of hydroxide ions at alkaline conditions and elevated temperatures. At this stage, our ...
