A ribbed porous carbon material (1) is a one piece molded product containing carbon fibers (5) and having a rib portion ( 2) and a web portion (3), in which the carbon fibers (5) are oriented in the rib portion (2) along the direction of the thickness of the web portion (3), while the carbon fibers (5) are oriented in the web portion (3) along the direction of the plane of the web portion (3) and along the direction perpendicular to the rib portion (2).

Flat plate-like ribbed porous carbon material and manufacturing method

Flat plate-like ribbed porous carbon material

An electrode for a living body comprises a main body consisting of a flexible sheet of graphite and the whole of the electrode is made substantially transparent in regard to X rays so that the electrode is not a hindrance to an X-ray inspection.

X ray-transparent electrode for a living body

Disclosed herein is an electrode substrate for a fuel cell, wherein at least a part of the electrode substrate comprises a flexible carbon material obtained from a composite material comprising carbon fibers of not less than 1 mm in mean length which have been treated at a temperature of not lower than 1000.degree. C. and a binding agent, the electrode substrate being contacted with flow channels of a reactant gas and the flexible carbon material comprising carbon lumps derived from the binding agent which are dispersed in the matrix of the carbon fibers and restrain a plurality of the carbon fibers and the carbon fibers slidably held to one another by the carbon lumps.

Electrode substrate for fuel cell

Disclosed herein is an electrode for a living body, which is used in a defibrillator and the like without hindering X-ray inspection, the main part of the electrode (hereinafter referred to as 'the electrode substrate') comprising a porous material composed of granular or fibrous carbon, or a flexible and porous material composed of fibrous carbon, the electrode being made to be transparent to X-ray.
