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...

Paper-based Microfluidic Fuel Cells

This work presents a paper-based membraneless microfluidic fuel cell. The device benefits from the laminar flow occurring in a porous material by capillarity to separately react with two parallel streams, anolyte and catholyte, without a separating membrane. Unlike conventional microfluidic fuel cells, the present device does not require external pumps or any other ancillary devices to operate,...

Study 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...

Alkaline 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...
