Abstract: The object of the present invention is to provide a conductive porous material that has a large specific surface area, that is not easily damaged by pressure, and that can be applied to a variety of applications; a polymer electrolyte fuel cell, and a method of manufacturing a conductive porous material. The conductive porous material is one which is an aggregate of fibrous substances comprising first conductive materials, and second conductive materials that connect between the first conductive materials, and its specific surface area is 100 m2/g or more, and its thickness retention rate after pressing at 2 MPa is 60% or more. Such a conductive porous material can be manufactured by spinning a spinning solution containing a first conductive material and a carbonizable organic material to form a precursor fiber porous material in which precursor fibers are aggregated, and carbonizing the carbonizable organic material to convert it into a second conductive material.

Abstract: The base material for a gas diffusion electrode of the present invention comprises a nonwoven fabric containing conductive fibers that contain conductive particles at least in the inside of an organic resin, and is characterized in that a specific apparent Young's modulus of the base material for a gas diffusion electrode is 40 [MPa/(g/cm3)] or more. Since the base material contains conductive fibers that contain conductive particles at least in the inside of an organic resin, it is flexible, and as a result, a polymer electrolyte membrane is not directly damaged. Further, since the specific apparent Young's modulus is 40 [MPa/(g/cm3)] or more, which indicates a high rigidity, and swelling and shrinkage of the polymer electrolyte membrane can be inhibited, cracking of the polymer electrolyte membrane can be avoided.
