▎ 摘　　要

NOVELTY - Gas diffusion layer slurry comprises a conductive agent, a hydrophobic agent, a pore-forming agent and a dispersing agent in a mass ratio of (2.3-4.8):(2.5-3.5):(0.35-0.55):(0.25-0.75). The pore-forming agent includes ammonium chloride, ammonium bicarbonate, polyvinyl butyral ester, and/or polyvinyl alcohol. The viscosity of the gas diffusion layer slurry is 2000-4500 cps. USE - The gas diffusion layer slurry is used for fuel cell stack in automobile, ship track traffic field, vehicle field is fuel cell technical route and power battery technical route. ADVANTAGE - The gas diffusion layer slurry has stable performance, uniform slurry, strong conductivity, small resistor and high porosity, is economical, simple technique, and can meet the continuous production requirement. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the gas diffusion layer slurry; and gas diffusion layer.
