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 کاملInvestigation of ion transport and water content properties in anion exchange membranes based on polysulfone for solid alkaline fuel cell application
In present research work, homogeneous anion exchange membranes based on polysulfone (QAPSFs) were prepared via chloromethylation, amination and alkalization. In amination step, trimethylamine and N,N,N',N'-tetramethyl-1,6-hexanediamine were used as amination and crosslinking agents, respectively. The chloromethylated polysulfone was characterized by 1HNMR spectroscopy and chloromethylation degr...
متن کاملPoly (Ether Ether Ketone) Based Anion Exchange Membrane for Solid Alkaline Fuel Cell: A Review
Solid alkaline fuel cell is employed by polymer anion exchange membrane (AEM) that is permeable to hydroxide ion. A number of polymers have been proposed for AEM which include polysulfone (PSF), poly (phenylene oxide) (PPO), and poly (ether ether ketone) (PEEK). The purpose of this paper was to conduct a critical review on the development of PEEK polymer as AEM, particu...
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 کاملModeling the effect of membrane conductivity on the performance of alkaline fuel cells
The present work proposes and demonstrates a methodology to capture the effect of operating conditions on ionic conductivity of membranes immersed in alkaline media. Based on reported experimental results for an anion exchange membrane (A-201 by Tokuyama) and a cation exchange membrane (Nafion 211), two novel expressions are developed for the ionic conductivity by incorporating the effects of s...
