High performance anion exchange ionomer for anion exchange membrane fuel cells
The anion exchange ionomer incorporated into the electrodes of an anion exchange membrane fuel cell (AEMFC) enhances anion transport in the catalyst layer of the electrode, and thus improves performance and durability of the AEMFC. In this work, a novel ionomer based on a triblock copolymer with high conductivity and good durability is synthesized successfully. The spectroscopy (such as H-NMR, ...
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 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 کاملAnion- or Cation-Exchange Membranes for NaBH4/H2O2 Fuel Cells?
Direct borohydride fuel cells (DBFC), which operate on sodium borohydride (NaBH4) as the fuel, and hydrogen peroxide (H2O2) as the oxidant, are receiving increasing attention. This is due to their promising use as power sources for space and underwater applications, where air is not available and gas storage poses obvious problems. One key factor to improve the performance of DBFCs concerns the...
متن کاملHybrid Anion and Proton Exchange Membrane Fuel Cells
A novel hybrid fuel cell is described using at least one electrode operating at high pH in an effort to use the high conductivity of Nafion and exploit the electrochemical advantages of high-pH operation. The electrochemical behavior of a hybrid anion exchange membrane (AEM)/proton exchange membrane (PEM) junction and corresponding fuel cell are presented. Two AEM/PEM junctions and fuel cells h...
