WOVEN FABRIC OF SPUN CARBON FIBER YARN AND METHOD FOR PRODUCING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a woven fabric of spun carbon fiber yarn, having excellent strength, low electric resistance in the thickness direction, useful as an electrode material for a polymer electrolyte-type fuel cell and having a thin thickness. PSOLUTION: The woven fabric of spun carbon fiber yarn has a thickness of 0.08-0.15 mm and a bulk density of 0.45-0.70 g/cmSP3/SPand satisfies the formulas (1) 150CSBA/SB400 and (2) 0.40CSBB/SB/CSBA/SB0.62 wherein CSBA/SB(dtex) is the thickness of the spun carbon fiber yarn in the warp direction and CSBB/SB(dtex) is the thickness of the spun carbon fiber yarn in the weft direction.
