Characteristics of perfluorosulfonic acid ion exchange in flow batteries

4 FAQs about [Characteristics of perfluorosulfonic acid ion exchange in flow batteries]

Can perfluorosulfonic acid be used in proton exchange membrane fuel cells?

Investigations of Dongyue Series Perfluorosulfonic Acid Membranes for Applications in Proton Exchange Membrane Fuel Cells (PEMFCs).

Are perfluorosulfonic membranes suitable for vanadium redox flow batteries?

A series of perfluorosulfonic membranes is screened for application in vanadium redox flow batteries (VRFB): membranes of constant thickness 50 µm with different ion-exchange capacities ranging from 0.56 to 1.15 mol eq. g −1.

Why are perfluorinated sulfonic acid membranes less selective?

However, perfluorinated sulfonic acid (PFSA) membranes—the most widely used PEM—have ultimate limitations of low proton selectivity to other active species because of their wide and randomly connected proton channels.

What is perfluorosulfonic acid membrane (PFSA)?

Its main function in fuel cells is to isolate oxidants in the cathode and reduce agents in the anode while simultaneously conducting cations [11, 12]. At present, perfluorosulfonic acid membrane (PFSA) is the most widely used and best-performing PEM in the current PEMFC market.
