Electrospun Composite Proton-Exchange and Anion-Exchange Membranes for Fuel Cells

Energies, 2021
A fuel cell is an electrochemical device that converts the chemical energy of a fuel and oxidant into electricity. Cation-exchange and anion-exchange membranes play an important role in hydrogen fed proton-exchange membrane (PEM) and anion-exchange ...

Preparation and characterization of PTFE based composite anion exchange membranes for alkaline fuel cells [PDF]

, 2012
In this paper, we report on the preparation of a novel type of PTFE based composite anion exchange membrane for alkaline fuel cells by a low-toxic and facile processing route. The membranes were synthesized by in-situ polymerization of a N-vinylformamide

Quaternary Ammonium-Bearing Perfluorinated Polymers for Anion Exchange Membrane Applications [PDF]

, 2020
Perfluorinated polymers are widely used in polymer electrolyte membranes because of their excellent ion conductivity, which are attributed to the well-defined morphologies resulting from their extremely hydrophobic main-chains and flexible hydrophilic ...

Application of Novel Anion-Exchange Blend Membranes (AEBMs) to Vanadium Redox Flow Batteries

Membranes, 2018
Both cation-exchange membranes and anion-exchange membranes are used as ion conducting membranes in vanadium redox flow batteries (VRFBs). Anion-exchange membranes (AEMs) are applied in vanadium redox flow batteries due to the high blocking property of ...

Influence of the ionic composition on the diffusion mass transfer of saccharides through a cation-exchange membrane [PDF]

, 2013
Recent studies have pointed out that the presence of salts can change significantly the membrane process performances because of the resulting modification of the neutral solutes transfer through the membrane.

Understanding the Effect of Triazole on Crosslinked PPO–SEBS-Based Anion Exchange Membranes for Water Electrolysis [PDF]

, 2023
For anion exchange membrane water electrolysis (AEMWE), two types of anion exchange membranes (AEMs) containing crosslinked poly(phenylene oxide) (PPO) and poly(styrene ethylene butylene styrene) (SEBS) were prepared with and without triazole. The impact
