GK® Perfluorosulfonic acid(PFSA) ion exchange membrane-Replace Nafion N117

Perfluorinated proton membrane have more than 1000 application cases in vanadium flow battery, hydrogen fuel celIs, hydrogen production via water electrolysis, ammo acid electrolyzer, copper recovery from etching solution, gold salt preparation ,chlorine dioxide generator,and electrodialysis etc.
Availability:
Quantity:

GK® PFSA membranes are non-reinforced films based on PFSA polymer, a perfluorosulfonic acid/PTFE copolymer in the acid (H+ ) form. GK® PFSA membranes are widely used for Proton Exchange Membrane (PEM) fuel cells and water electrolyzers. The membrane performs as a separator and solid electrolyte in a variety of electrochemical cells which require the membrane to selectively transport cations across the cell junction. The polymer is chemically resistant and durable. Widely used: vanadium battery, liquid flow battery, fuel cell, electrolysis water, hydrogen production and other fields.


Specifications:(More details, please check the specification column)

1. Roll

0.61m*100m
0.80m*100m

0.2m/0.3m/0.4m width, length at random(the order quantity should be achieve 50 square meters)

2. Sheet

Width: 0.30 m (min) to 1 m (max)
Length: 0.30 m (min) to 1 m (max)

Mark: The dimensions of the membrane supplied are based on dry film products, at 23°C and 50% relative humidity. The humidity and temperature will affect its size. Products that require pretreatment by our company are guaranteed to have a positive tolerance, and the products that require pretreatment are all sheets.


Package: The packaging of the film is wrapped in a small volume and has no coil core. As the size of the perfluoro ion membrane varies at different temperature and humidity, the NEPEM perfluoroionic membrane is protected by the hard protective film to facilitate the spraying of MEA and the stability of the size reduction. The outer packaging is packed in plastic barrels or hard cartons. Please contact the salesperson for the special size and packing.

Capable of scrubbing out hydrogen fluoride and other acidic combustion products. Treatment, storage, transportation, and disposal must be in accordance with applicable federal, state/provincial and local regulations. Our company provides full recovery service for waste materials of fluorine ion membrane. For details, please contact sales staff of our company.


Properties of PFSA membranes.


GKPEM-301 Series (Hydrogen Fuel Cell)

EPTFE (expanded polytetrafluoroethylene) microporous reinforcing material was added to the traditional proton exchange membrane. which has the characteristics of high strength. high conductivity and low ion permeability.

11

GKPEM-11 Series (Vanadium Flow Batteries)

The strength, moisture retention by and introducing vanadium special resistance nano-graphene of ion exchangematerials into the membranes tape were casting improved process. 

22

GKPEM-41 Series (Electrolysis)

Unique tape casting process with appropriate molecular weight and ion exchange capacity of pernuorosulfonic acid resin is used to form homogeneous membrane with uniform thickness. It is widely used in electrolytic chlorine dioxide generator, etching solution recovery copper, gold salt preparation. amino acid refining, caustic soda preparation. electrodialysis and other electrolytic industries. 

33

GKPEM-51 Series (Water Treatment)

Using high strength PTFE mesh as supporting layer, with perfluorosulfonic acid resin with the most suitable molecular weight and ion exchange capacity, it has super chemical resistance and durability, and is widely used in the treatment of high salt wastewater, electrodialysis and othe water treatment fields.

44

GKPEM-W Series (Hydrogen-Rich Water Cup Membrane)

Perfluorosulfonic acid resin with high purity, the most suitable molecular weight and ion exchange capacity and unique additive technology are used to reduce the impact on the taste and prolong the service life of the membrane.
