AB - In this study, graphite composites were fabricated by warm pres molding method to realize comercialization ofPEM fuel cells. Graphite composites have ben considered as alternative economic materials for bipolar plate of PEMfuel cells. Graphite powder that enables to provide electrical conductivity was selected as the main substance. Thegraphite powder was mixed with phenolic resin and the mixture was pressed using a warm press method.First of all, the graphite powder was pulverized with a ball mill for the dense packing of composite. As the bal milingtime increases, the average size of particles decreases and the size distribution becomes narow. This alows forimprovement of the uniformity of graphite composite. However, the surface electrical resistivity of graphite compositethe surface due to the friction and collision of particles during pulverizing. We found that the contact electrical resistiv-ity of graphite particles increases as the particle size decreases.The contact electrical resistivity of graphite powders was reduced due to high molding presure by warm pres mold-ing. This leads to improvement of the mechanical properties of graphite composite. Hydrogen gas impermeability wasmeasured with the graphite composite, showing a possibility of the application for bipolar plate in fuel cell. And, I-Vcurves of the graphite composite bipolar plate exhibit a similar performance to the graphite bipolar plate.
