Title:
多孔質電極基材とその製造方法
Document Type and Number:
Japanese Patent JP5526969
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a porous electrode base material and its manufacturing method, which can be manufactured at a low cost, and offer a high thickness precision and surface smoothness, and which has sufficient handleability, air permeability and electrical conductivity.SOLUTION: A method of manufacturing a porous electrode base material with pieces of carbon short fiber (A) connected by 3D-network-texture carbon fiber (B) includes the steps of: using carbon short fiber (A), and carbon-fiber-precursor short fiber (b) consisting of polyacrylonitrile polymer/phenol resin and fibrillated by beating to manufacture a precursor sheet, in which the carbon short fiber (A) and carbon fiber precursor short fiber (b') resulting from the fibrillation of the carbon-fiber-precursor short fiber (b) by beating are distributed; and carbonizing the precursor sheet.
