Polysulfone-based Anion Exchange Membranes for Potential Application in Solid Alkaline Fuel Cells
In present research work, anion exchange membranes based on quaternized polysulfone with ammonium cation moieties (QAPSF) were prepared by chloromethylation, amination and alkalization. The chloromethylated polysulfone were characterized by 1HNMR spectroscopy and functionalization degree was determined according to peak area integration. Ion transport properties (ionic conductivity, ion exchang...
متن کاملAlkaline Anion Exchange Membranes for Fuel Cells- a Patent Review
Recently, Alkaline Polymer Electrolyte Membrane Fuel Cells (APEMFCs) have been attracting worldwide attention mainly due to the prospect of using non–platinum–group metal catalysts. In addition, there is growing evidence that these fuel cells can operate with the presence of carbonate. This mini review will introduce the state–of–the–art in understanding of alkaline anion–exchange membranes (AA...
متن کاملTunable High-Molecular-Weight Anion- Exchange Membranes for Alkaline Fuel Cells
Tunable alkaline anion-exchange membranes based on QPMBV are synthesized using a bottom-up approach, miniemulsion copolymerization, which can incorporate functional groups into the copolymers with designated composition and high molecular weight. The mechanical and electrochemical properties of the obtained QPMBV membranes are tuned by varying the composition. It is found that the ion exchange ...
متن کاملAlkaline anion-exchange radiation-grafted membranes for possible electrochemical application in fuel cells
Vinylbenzyl chloride was grafted onto PVDF and FEP polymer films using the radiation-grafting methodology. Subsequent reaction with trimethylamine and ion-exchange with potassium hydroxide yields alkaline anion-exchange membranes that are capable of conducting hydroxide ions; such membranes may be suitable for use in low temperature direct methanol fuel cells for portable devices. The PVDF base...
متن کاملProspects for Alkaline Anion-Exchange Membranes in Low Temperature Fuel Cells
This article introduces the radical approach of applying alkaline anion-exchange membranes (AAEMs) to meet the current challenges with regards to direct methanol fuel cells (DMFCs). A review of the literature is presented with regards to the testing of fuel cells with alkaline membranes (fuelled with hydrogen or methanol) and also to candidate alkaline anionexchange membranes for such an applic...
