摘要： One porous electrode base material for a polymer electrolyte fuel cell comprises: short carbon fibers which are dispersed in random directions in a substantially two-dimensional plane and have a fiber diameter of 3 to 9 µm; an amorphous resin carbide which binds said short carbon fibers; and a filamentary resin carbide which further cross-links said short carbon fibers, wherein said porous electrode base material has a thickness of 150 µm or less. Furthermore, another porous electrode base material for a polymer electrolyte fuel cell comprises: short carbon fibers which are dispersed in random directions in a substantially two-dimensional plane and have a fiber diameter of 3 to 9 µm; an amorphous resin carbide which binds said short carbon fibers; and a network resin carbide having a minimum fiber diameter of 3 µm or less which further cross-links said short carbon fibers.

摘要： An apparatus and process for producing a resin-impregnated cured sheet which comprises continuously curing a continuous uncured fibrous sheet obtained by forming short fibers into a sheet and impregnating it with an uncured resin; and an apparatus and process for producing a carbonaceous material sheet which comprises continuously carbonizing the cured sheet. The carbonaceous material sheet is excellent in handleability and transportability and is capable of being wound. The continuous uncured fibrous sheet (1a) is conveyed by a conveying means comprising at least one pair of rotating belts (2) each comprising a drive roll (2a), a driven roll (2b), and an endless belt (2c) running on and between these rolls, and the resin is cured between heating/pressing rolls or between the endless belts. The resultant resin-impregnated cured sheet is then continuously conveyed in a horizontal direction to a carbonization chamber and carbonized therein to produce a carbonaceous material sheet.
