Studies on particle grade in the preparation of conductive composite bipolar plate

Preparing conductive composite bipolar plate for fuel cell by mold pressing is a promising research direction. It is very important that conductivity and mechanics intension of bipolar plate must meet using desire at the same time. On the basis of basic theory and calculated result of single diameter particles packing, binary particles grade and multidimensional particles grade, the technique of improving conductive composite conductivity by particles grade was acquired. The sound particles grade can increase conductive composite conductivity in the using less conductive fillers.
