Paper Title:
The Development of the Composite Materials for the Bipolar Plate of the Fuel Cell
  Abstract

The paper was to investigate the development of the graphite/phenolic resin composite materials that were fabricated by compression molding for the bipolar plate of the fuel cell. Effect of the different amounts of resin and the graphite powder size on the porosity, density, bending strength, and electrical resistance of the composites would be analyzed. In addition, the composites of the bipolar plates would be machined into the groove channel using high speed milling, which then assembles into single fuel cell. The I-V performance of the single fuel cell would be also discussed. The experimental results showed that when the larger amount of resin was employed, the resulting composites had a lower porosity, a larger electrical resistance, and a higher bending strength. 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 were fabricated into a single fuel cell, which displays a relatively better I-V performance.
