Patent number: 7410719Abstract: A porous carbon base material includes a sheet containing carbon short fibers dispersed randomly and a carbonized resin, in which the carbon short fibers are bound by the carbonized resin and the volume of pores having a pore diameter of 10 ?m or less is 0.05 to 0.16 cc/g. A method for producing this porous carbon base material includes intermittently transporting a precursor fiber sheet including short carbon fibers dispersed randomly and a resin to a space between heated plates, subjecting the precursor to a heating and pressuring treatment by the heated plates while the transformation stops, carrying out the transportation of the sheet after the treatment, and then carrying out a heat treatment, to thereby carbonize the resin in the sheet.Type: GrantFiled: March 25, 2004Date of Patent: August 12, 2008Assignee: Toray Industries, Inc.Inventors: Takashi Chida, Kenya Okada, Mikio Inoue, Shinya Isoi
