Product Detailed:

GN Perfluorinated Proton-exchange membrane made by General energy Co.,Ltd. GN is a new kind of PEM. GN is made by a new resin flow technology. This new technology can combine with adulterate technology. Thus GN has many outstanding features, GN-21X series of proton exchange membrane with special formula of graphene with high conductivity in the casting process. After the test, the GN-21X type proton exchange membrane still maintained a high electrochemical performance by using the new type of special graphite mixture ratio of 100 degrees Celsius. The water retention property of the membrane and the electrochemical properties of the high temperature and high temperature were significantly higher than those of the conventional one. GN-21XC series of ionic membrane using 1000 equivalent of high quality and high fluorine ion exchange resin as raw material which has stable performance, and adulterate the optimal proportion of special graphene elements, so as to ensure the high conductivity, high resistance, high water retention. The GN-21XC series of perfluorinated ion exchange membrane is especially suitable for the proton exchange membrane for hydrogen air fuel cells and direct methanol fuel cells.
