Electrodialysis (ED) should have played important roles ...
Nowadays, five major types of fuel cells can be distinguished by the type of electrolyte: alkaline fuel cells (AFCs), proton-exchange membrane fuel cells (PEMFCs), solid oxide fuel cells (SOFCs), phosphoric acid fuel cells (PACFs) and molten carbonate fuel cells (MCFCs). The AFC (using...
Anion exchanger 1 (AE1, band 3) is a major membrane protein of red blood cells and plays a key role in acid-base homeostasis, urine acidification, red blood cell shape regulation, and removal of carbon dioxide during respiration. Though structures of the transmembrane domain (TMD) of three ...
ion exchange[′ī‚än iks‚chānj] (physical chemistry) A chemical reaction in which mobile hydrated ions of a solid are exchanged, equivalent for equivalent, for ions of like charge in solution; the solid has an open, fishnetlike structure, and the mobile ions neutralize the charged...
The anion exchange membrane is stable in physical properties, excellent in alkali resistance and high in ion exchange capacity, and a linear chain structure of the anion exchange membrane can be reversibly adjusted under the effect of ultraviolet light/visible light, thus ionic conductance and ...
For hydroxide exchange membrane fuel cell or hydroxide exchange electrolysis applications or any other application that requires the hydroxide ion transfer across the membrane, the membrane should be converted from bicarbonate form into OH- form for optimal conductivity. To convert the membrane to OH- ...
Through-plane (TP) conducting pathways in anion-exchange membranes (AEMs) are desirable for AEM fuel cells as they serve as short and efficient routes for hydroxide ion transport between electrodes, improving power output. Electric and magnetic fields ha
PURPOSE:To provide an anion exchange membrane having excellent alkali resistance by the reaction of a film comprising a specific polymeric material with a specified amine, with an alcoholate and subsequently with an alkyl iodine. CONSTITUTION:A film comprising a polymeric material of formula I (X ...
Anion exchange membrane (AEM) is a solid polymer membrane that contains positive ionic groups, e.g., quaternary ammonium (QA) groups such as R–N+(CH3)3, and mobile negatively charged anions, usually halides or OH− anions. From: Comprehensive Renewable Energy (Second Edition), 2022 ...
