We have developed cost- effective graphite bipolar plates which requires the use of advanced bipolar plates with high electrical conductivity and good mechanical strength. It is refined by high-pressure forming, vacuum impregnation, and high-temperature heat treatment, our bipolar plate has the characteristics of wear resistance, temperature resistance, pressure resistance, corrosion resistance, creep resistance, oil-free self-lubrication, small expansion coefficient, and superior sealing performance.
We can machine the bipolar plates on both sides with flow fields, or machine single side or provide unmachined blank plates as well. All graphite plates could be machined as per your detailed design.
