Abstract
The invention discloses a spinning solution for a fuel cell and a preparation method of carbon paper of the spinning solution, and belongs to the technical field of carbon paper preparation. The spinning solution comprises raw materials, a solvent and an auxiliary; the mass ratio of the raw material to the solvent to the auxiliary agent is (20-50): (60-100): (1-5); the raw material comprises polyacrylonitrile; the solvent comprises one or more of dimethyl amide, dimethyl sulfoxide, sodium thiocyanate or zinc chloride; and the auxiliary agent comprises one or more of dimethyl phthalate, diethyl phthalate, di-n-butyl phthalate, dioctyl phthalate or butyl benzyl phthalate. The spinning liquid is jetted on a substrate by jet spinning to form organic cellosilk firstly and then form the carbon fiber paper. The carbon fiber paper with good thickness consistency prepared by the method has good capability of conducting electrons, water and gas, in addition, the preparation process is simple and controllable, the cost is reduced, and batch production can be realized.
