An objective of the invention is to suppress a loosening of strands at both ends of a carbonic fiber woven fabric which is generated as a result of a repetitive rolling and unrolling. The present invention is to conduct an anti-loosening treatment of carbo...

A fuel cell-use carbon fiber woven fabric, especially a carbon fiber woven fabric preferably used for the electrode diffusion layer of an electrode element in a fuel cell. The electrode diffusion layer of an electrode element in a fuel cell, requiring cond...

A conductive carbonaceous-fiber sheet has a thickness of from 0.05 to 1 mm, a weight per a unit area of from 60 to 250 g/m, a bending resistance (L) as determined by the 45 DEG Cantilever method of 6 cm or higher and an in-plane volume resistivity of 0.2 O...
