Investigations of Dongyue Series Perfluorosulfonic Acid Membranes for Applications in Proton Exchange Membrane Fuel Cells (PEMFCs).
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.
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.
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.
Our solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
