Title:
ELECTROCONDUCTIVE POROUS BODY, SOLID POLYMER FUEL CELL, AND METHOD FOR MANUFACTURING ELECTROCONDUCTIVE POROUS BODY
Document Type and Number:
WIPO Patent Application WO/2015/146984
Kind Code:
A1
Abstract:
　The present invention addresses the problem of providing: an electroconductive porous body that has a large specific surface area, that does not readily break under pressure, and that can be applied to a variety of applications; a solid polymer fuel cell; and a method for manufacturing an electroconductive porous body. This electroconductive porous body is obtained by aggregating a fibrous material having a first electroconductive material and a second electroconductive material that links spaces in the first electroconductive material, the electroconductive porous body having a specific surface area of 100 m2/g or above, and a thickness retention rate of 60% or above after application of pressure at 2 MPa. Such an electroconductive porous body can be manufactured by spinning a spinning solution containing the first electroconductive material and a carbonizable organic material, forming a precursor fiber porous body in which precursor fibers are aggregated, and subsequently carbonizing the carbonizable organic material to obtain the second electroconductive material.
