Title:
POROUS BASE MATERIAL, POROUS ELECTRODE, CARBON FIBER PAPER, METHOD FOR MANUFACTURING CARBON FIBER PAPER, AND METHOD FOR MANUFACTURING POROUS BASE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/016626
Kind Code:
A1
Abstract:
A porous base material and porous electrode provided with both gas permeability suitable for a gas diffusion layer for a fuel cell vehicle and mechanical strength that can withstand continuous roll to roll processing, and a porous electrode with superior diffusion properties for electrolytes suitable for electrodes used in redox flow batteries, have been desired. Provided is a porous base material wherein carbon fiber (A) with an average fiber diameter of 10 - 20 µm, average fiber length of 2 - 30 mm, modulus of elasticity in tension of 200 - 600 GPa and tensile strength of 3000 - 7000 MPa is bonded by a carbon binder (D).
