Notes:
The paper was to investigate the development of the graphite/phenolic resin compositematerials that were fabricated by compression molding for the bipolar plate of the fuel cell. Effectof the different amounts of resin and the graphite powder size on the porosity, density, bendingstrength, and electrical resistance of the composites would be analyzed. In addition, the compositesof the bipolar plates would be machined into the groove channel using high speed milling, whichthen assembles into single fuel cell. The I-V performance of the single fuel cell would be alsodiscussed.The experimental results showed that when the larger amount of resin was employed, theresulting composites had a lower porosity, a larger electrical resistance, and a higher bendingstrength. The graphite/resin composites showed a good machinability during the high-speed milling.Finally, the graphite/resin composites of bipolar plates containing 25-30 vol. % phenolic resins werefabricated into a single fuel cell, which displays a relatively better I-V performance
