▎ 摘  要

NOVELTY - Method for continuously forming and preparing graphite composite bipolar plate involves (a) pulling one end of the bipolar plate aggregate coiled material (1) into the resin groove (3) through four first guide rollers (2), (b) drying the resin solution (4) to remove the solvent in the 80-90degrees Celsius drying roller (5), (c) compacting to the thickness of 1.2-2 mm by the compacting roller, (d) cutting the finished product by the cutting machine (13) after hot pressing by the hot press, (e) filling the inner sides of the resin tank and the slurry bin with resin solution and slurry, and (f) using graphene slurry, graphene, nano-tube slurry and natural graphite, and carbon nanotube slurry USE - Method for continuously forming and preparing graphite composite bipolar plate used in liquid flow battery and fuel cell. Can also be used in metal bipolar plate and composite graphite bipolar plate. ADVANTAGE - The bipolar plate has very high mechanical strength, at the same time, the fiber cloth, conductive graphite felt and graphite feels are present in the developed conductive network, which can greatly reduce the resistivity of the bipolar plate. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating method for continuous molding to prepare a graphite composite bipolar plate (Drawing includes non-English language text). Bipolar plate aggregate coiled material (1) First guide rollers (2) Resin groove (3) Resin solution (4) Drying roller (5)
