Title:
FUEL CELL COMPOSITE ELECTRODE PLATE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/236235
Kind Code:
A1
Abstract:
Disclosed in the present application are a fuel cell composite electrode plate and a preparation method therefor. The preparation method comprises the following steps: S01, uniformly mixing 40%-90% of graphite matrix, 5%-50% of resin, and 0-40% of conductive filler to obtain a mixture, and carrying out multi-channel rolling on the mixture to obtain a prefabricated plate, a plurality of convex points being arranged on a roller of the first-channel rolling in the multi-channel rolling; and S02, placing the prefabricated plate in step S01 on the surface of a conductive substrate, rolling for 1-15 min at the temperature of 150°C-450°C, and cooling to room temperature to obtain the fuel cell composite electrode plate, wherein patterns are arranged on the roller for rolling, and the percentage is weight percentage. According to the present application, the problem that it is difficult to form the electrode plate at the thinnest position can be solved, and the prepared composite electrode plate is good in forming strength and can meet the use requirements of the fuel cell. The method is simple, low in production cost, high in production efficiency and easy for large-scale production.
