Title:
CARBON-FIBER NONWOVEN CLOTH AND GAS DIFFUSION ELECTRODE FOR POLYMER ELECTROLYTE FUEL CELL USING SAME, POLYMER ELECTROLYTE FUEL CELL, METHOD FOR MANUFACTURING CARBON-FIBER NONWOVEN CLOTH, AND COMPOSITE SHEET
Document Type and Number:
WIPO Patent Application WO/2014/087887
Kind Code:
A1
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.
