Duratight belongs to the earliest manufactures with involvement in Bipolar Plate R & D and productions, Years of experience in this field have enabled us to provide our customers with the best value-for-money delivery solution.

The electrode plate of fuel cell is one of the key components of PEMFC. Its function is to connect individual cells in series and assemble them into a battery stack. At the same time, it is also responsible for introducing reaction gas into fuel cell, conducting current, heat dissipation and drainage of PEMFC, its performance directly affects the output power and service life of the whole battery stack. The Composite Plate is made by mixing Polymer Resin and graphite powder into composite material, and then by compression molding to make bipolar plate, which has the advantages of good conductivity, corrosion resistance, dimensional stability and flame retardancy. Compared with the graphite plate, composite carbon plate and surface-modified metal plate on the market, our products have the following advantages:

 excellent conductivity, corrosion resistance, gas resistance, chemical stability and High Mechanical Strength;

Moreover, it is easy to be processed to ensure that the reaction gas is evenly distributed through the flow field channel (flow field)

 In addition, the bipolar plate is also a good conductor of heat to ensure that the temperature of the battery stack is evenly distributed and the waste heat is discharged smoothly,

Light Density would improve the energy density and power density of the battery pack effectively.

In addition processing, the size of the battery plate tolerance is less than 0.02 mm, and Duratight has advanced processing technology and testing equipment, can ensure the quality of the plate. The concrete size may according to the customer request processing.

Graphite is widely used in various fields, as professional supplier, we will recommend and supply the most suitable grade for different fields. in addition, Duratight owns different Surface Treatments to meet special requirements. Welcome you to share your exact demand to our team.
