Aromatic polyelectrolytes via polyacylation of pre-quaternized monomers for alkaline fuel cells†
To overcome alkali-resistant and synthetic hurdles to alkaline anion-exchange membranes (AAEMs) for alkaline fuel cells, the polyacylation of pre-quaternized monomers as a straightforward and versatile approach has been proposed for the first time. Via this approach, novel aromatic anion-exchange polyelectrolytes featuring a long pendent spacer (i.e., –O–(CH2)4–) instead of a conventional benzy...

متن کاملPolysulfone-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 کاملStudy of Alkaline Electrodes for Hybrid Polymer Electrolyte Fuel Cells
Hybrid polymer electrolyte fuel cells combine a proton exchange membrane PEM and anion exchange membrane AEM and exhibit unique advantages. The electrochemical performance and current limitations of a hybrid cell with an alkaline electrode fabricated on a Nafion membrane was characterized at 70°C as a function of relative humidity. To separate the individual characteristics of the AEM anode and...
