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...
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 کاملReactive oxygen species accelerate degradation of anion exchange membranes based on polyphenylene oxide in alkaline environments.
Anion exchange membranes (AEM) based on polyphenylene oxide (PPO) suffered quaternary-ammonium-cation-site degradation in alkaline environments. Surprisingly, the degradation rate was considerably faster in the presence of molecular oxygen. We postulated that the AEM cation-site catalyzes the reduction of dioxygen by hydroxide ions to yield the superoxide anion radical and the highly reactive h...
متن کاملInvestigations of Conductivity in FEP-Based Radiation-Grafted Alkaline Anion-Exchange Membranes
A series of radiation-grafted alkaline anion-exchange membranes (AAEMs) with degrees of grafting (by mass) in the range 20 – 26% were produced and characterised. Conductivities (from impedance spectroscopy) up to 0.023 ± 0.001 S cm at 50 ± 1°C were demonstrated, which are between 20 – 50% of values for the commercial acidform membrane Nafion-115 (σ = 0.045 ± 0.004 (65°C) – 0.104 ± 0.008 (50 ± 1...
متن کاملDevelopment of Imidazolium-type Anion-Exchange Membranes for Alkaline Fuel Cell Application
This study reports the development of imidazolium-type anion exchange membranes (Im-AEMs) based on the functionalization of bromomethylated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO) using 1-methylimdazole. Aromatic polymers bearing bromomethyl, instead of chloromethyl, functional groups were employed as base materials to avoid complicated chloromethylation which require toxic reagents. H NM...
