Proton Exchange Membrane for Flow Battery
Product Description
The HPM series proton exchange membrane for flow battery is reinforced perfluorosulfonic acid proton exchange membrane (PEM). It has properties of high proton conductivity, high stability, and high vanadium ion barrier in both acidic and corrosive environments, and is widely used in flow batteries. It is identified by membrane type and identification number (batch number).
