    Abstract: Provided is a carbon-fiber nonwoven cloth with low resistance to gases or liquids passing through, and low resistance in the thickness direction to heat or electricity, which is particularly appropriate for a gas diffusion electrode of a polymer electrolyte fuel cell; the cloth having an air gap with a diameter of at least 20 µm, at least some of the carbon fibers being continuous from one surface to the other surface, and the apparent density being 0.2-1. g/cm3, or, having an air gap with a diameter of at least 20 µm and at least some of the carbon fibers being mutually interlaced, and further, at least some of the carbon fibers being oriented toward the thickness direction and the apparent density being 0.2-1.0 g/cm3.

    Abstract: This invention provides a leather-like sheet excellent in hand softness and appearance durability, as a composite sheet consisting of a nonwoven fabric composed of ultrafine long fibers in which ultrafine fibers with a fiber fineness of 0.0001 to 0.5 dtex are entangled with each other, and a woven or knitted fabric, characterized in that at least some of the aforementioned ultrafine fibers pass through the woven or knitted fabric, that the appearance is grade 3 or higher while the abrasion loss is 10 mg or less in the evaluation of abrasion resistance, and that the sheet is substantially composed of only a fiber material of a non-elastic polymer.

    Abstract: The present invention addresses the problem of providing a solid-polymer fuel cell in which a grooved gas-diffusion electrode material is used, the solid-polymer fuel cell exhibiting satisfactory water discharging properties and excellent power generation performance even when a parallel model is used as a separator in power generation conditions involving particularly high humidity. The present invention is a solid-polymer fuel cell having a gas diffusion electrode with a carbon fiber nonwoven fabric as the base material, and a separator in which parallel linear channels are formed, wherein: the carbon fiber nonwoven fabric has corrugated indentations and protrusions in which linear ridges and linear grooves are alternately repeated; the optical transparency is the same for the ridges and the grooves; and the gas diffusion electrode and the separator are disposed so that the surface of the carbon fiber nonwoven fabric on which the indentations and protrusions are formed faces the surface of the separator on which the channels are formed, and that the extension direction of the ridges and grooves is aligned with the extension direction of the channels in the separator.
