Abstract: First, the present invention involves adding a curing catalyst to a phenolic resin, polyvinyl alcohol, a pore-forming agent, and a cross-linking agent, and mixing, casting, heating, and drying the same. Next, the plate-shaped porous phenolic resin obtained thereby which has uniform consecutive macropores having an average pore diameter in the range of 3 to 35 ?m and formed in a three-dimensional network pattern is immersed with an organic solvent. Thereafter, this block is extracted and pressure is applied thereto. It is possible to obtain plate-shaped activated carbon for use in an electrode of a power-storage device by carbonizing and activating a block which has undergone this procedure by keeping the same at an increased temperature.

Abstract: An electrode for use in a fuel cell comprises a flexible carbon-fiber nonwoven fabric and a fuel cell catalyst, such as a metal catalyst or a carbon alloy catalyst, supported on the surfaces of the carbon fibers constituting the flexible carbon-fiber nonwoven fabric. The flexible carbon-fiber nonwoven fabric is formed by carbonizing a nonwoven fabric obtained by electrospinning a composition containing: an electrospinnable macromolecular substance; an organic compound that is different from the macromolecular substance; and a transition metal. This structure allows the provision of an electrode, for use in a fuel cell, which uses a flexible carbon-fiber nonwoven fabric as a substrate and combines the functions of a gas-diffusion layer and an electrocatalyst layer.
