  • PROTON EXCHANGE MEMBRANE FUEL CELL BIPOLAR PLATE
    Publication number: 20080050618
    Abstract: A proton exchange membrane fuel cell bipolar plate molded from a composition that includes a graphite powder, a thermosetting resin and an internal mold release agent has specific surface characteristics which endow the bipolar plate with a high hydrophilicity that enables water formed during power generation by the fuel cell to be easily removed. The bipolar plate also has a low contact resistance with electrodes in the fuel cell, and the shapes of flow channels on the bipolar plate remain intact.

  • Fuel cell separator
    Publication number: 20050130022
    Abstract: Fuel cell separators which are made by shaping a composition that includes a thermosetting resin, an artificial graphite with an average particle size of 20 to 70 ?m and an internal mold release agent and which have a surface with an average roughness Ra of 1.0 to 5.0 ?m are very hydrophilic, and thus facilitate the removal of water that forms during power generation by the fuel cell. Such separators also have a low contact resistance with electrodes in the fuel cell.
