摘要： In a separator for a fuel cell and a method of producing a separator for a fuel cell according to the invention, bondcarbon is used in which composition ratios are set to 60 to 90 wt. % (preferably, 70 to 87 wt. %) of graphite powder having an average diameter in a range of 15 to 125 &mgr;m (preferably, 40 to 100 &mgr;m), and 10 to 40 wt. % (preferably, 13 to 30 wt. %) of a thermosetting resin. The compound is previously cold-molded into a shape similar to a final molded shape. The preliminary molded member is then placed in a mold, and then molded into a separator of the final shape by applying a pressure of a range of 10 to 100 MPa. The surface roughness Ra of at least a portion of the separator contacting with an electrode is set to a range of 0.1 to 0.5 &mgr;m. According to this configuration, fluidity and moldability are excellent, the contact resistance can be set to a value lower than a requested value while ensuring strength sufficient for preventing the separator from suffering a damage such as a breakage due to vibrations or the like, and the low contact resistance can be stably maintained.

摘要： A yarn which is configured by using expanded graphite and polytetrafluoroethylene (PTEE) is provided while improving the yarn so that the expanded graphite functioning as a core member is not exposed and it can be simply produced. The yarn is formed by: forming a base member configured by enveloping an expanded graphite sheet member with a PTEE film, in a state where the PTEE film and the expanded graphite sheet member are aligned with each other in longitudinal direction; and twisting the base member. The base member has an approximately circular sectional shape, and is configured by enveloping the expanded graphite sheet member having a rounded sectional shape with the PTEE film which is rounded in a pipe-like shape.
