Industrial production process of flexible carbon-based bipolar plate of fuel cell

Abstract

The invention mainly discloses an industrial production process of a flexible carbon-based bipolar plate of a fuel cell. The industrial production process sequentially comprises the steps of S1 carrying out a raw material plate pretreatment process; S2 after pretreatment of the raw material plate is completed, entering a single-pole plate forming process; S3 carrying out a monopolar plate cleaningprocedure; S4 carrying out a unipolar plate tidying process; S5 carrying out a single-pole plate airtight treatment process; s6 carrying out a cleaning process on the unipolar plate subjected to airtight treatment and a tidying tool together; S7 carrying out a unipolar plate leveling process; S8 carrying out a polar plate gluing process; S9 carrying out a bipolar plate synthesis process; S10 carrying out a bipolar plate curing process; and S11 carrying out a bipolar plate detection process. The production efficiency is improved, the product percent of pass is increased, the labor intensityis reduced, the manufacturing cost is reduced, and commercialized and large-scale manufacturing of the bipolar plate is realized.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to an industrialized production process of flexible carbon-based bipolar plates for fuel cells. Background technique [0002] A fuel cell is one of many electrochemical power sources. More precisely, a fuel cell is a process module that directly converts the energy of a chemical reaction into electrical energy. The fuel cell is very different from the general battery. The active material of the general battery is stored inside the battery, so the amount of the stored active material determines the capacity of the battery, and the active material of the fuel cell can be continuously Input. Fuel cells mainly include proton exchange membrane fuel cells, alkaline fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, solid oxide fuel cells and so on. Among them, proton exchange membrane fuel cells are widely used, especially proton exchange membrane fuel cells using h...

Problems solved by technology

Therefore, due to the limitation of material characteristics, the current production of flexible carbon-based bipolar plates is done manually, and the production process cannot be automated or even semi-automated.

Due to the manual operation, the whole process requires high skills of the operators, and it is difficult to effectively guarantee the consistency of product quality. At the same time, due to the inability to realize large-scale production, the efficiency is low, the labor intensity is high, and the loss is high, which greatly increases costs in the manufacturing process
