 vanadium redox battery ion exchange film
Vanadium Redox Batteries

N -11X N Perfluorinated Proton-exchange membrane made by our own advanced machine. N  is a new kind of PEM. N  is made by a new resin flow technology. This new technology can combine With adulterate technology. Thus N  has many outstanding features, It not only has the high tensile strength, high selection, isotropy , high conductance; but also has the effect of self-humidifying and with low Linear Expansion. It is very suitable for Fuel cell, vanadium redox batteries, electrolyzer, lectrodialysis,
electrochemical sensors.It has outstanding features as the solid electrolyte
N  membrane has been tested over 100000 hour in fuel cell and 50000
hour in VRB.Our general company is the expert in ion exchange membrane
area. Our company has a long membrane making history over 10 years.
And our film have been hold the 40% of perflourinated ion  exchange membrane market in china. We are building “China Ion exchange Membrane Technology Center” with Xiamen University.The production capacity of  membrane will arrive 300,000 square meters to 2013.
