Application:

The PFSA membranes for Vanadium Redox Flow Battery are non-reinforced films based on PFSA polymer, a perfluorosulfonic acid in the acid (H+) form. Our PFSA membranes perform as a solid polymer electrolyte in fuel cells and other applications in electrochemistry and separation technology for a variety of electrochemical process, especially in the redox flow battery (RFB).
The membranes show significant improvements in features such as better resistance to chemical attack and longer operating durability in the redox flow battery (RFB).
The Vanadium Redox Battery(VRB) is a redox battery that uses vanadium as an active material to circulate in a liquid state.

Packaging:
The membrane combined with the coversheet eliminates rapid changes in the membrane's water content, and stabilizes the dimensions of the membrane when removed from the roll,the membrane should be easily peeled off from the coversheet during this step.

The membrane for cut pieces will depend on the size and quantity of the customer's order requirements. Generally, the flat membranes are directly winded into a small roll, and the membranes are protected with a polyethylene wrap and inner packaging. The standard product specifications for membrane rolls include:
Width:80cm standard width, other widths are available on special order. Length:100-meter standard roll length, other non-standard lengths are feasible to meet orders of the customers. The membrane pieces or rolls can be cut to non-standard sizes, please contact our sales staff for details and availability.
