Graphite Bipolar Plate
NAME: Graphite Bipolar Plate

                                                                           Graphite Bipolar Plate for fuel cell 

     

    We have developed cost- effective graphite bipolar plates for PEMFC which requires the use of advanced bipolar plates with high electrical conductivity and good mechanical strength. Our bipolar plates allow fuel cells to operate at high temperatures and have excellent electrical and thermal conductivity.


    We offer the graphite material with impregnated resin in order to achieve gas impermeability and high strength. But the material retains the favorable properties of graphite in terms of high electrical conductivity and high thermal conductivity.


     We can machine the  bipolar plates on both sides with flow fields, or machine single side or provide  blank plates as well. All graphite plates could be machined as per your detailed design.
