Embodiment Construction

[0039] An industrial production process of a flexible carbon-based bipolar plate for a fuel cell, comprising the following steps in sequence,

[0040] S1. The pretreatment process of the raw material sheet includes heating, dehumidifying and drying the flexible carbon-based raw material sheet sequentially, and cleaning the dust on the surface to obtain a dry and clean raw material sheet;

[0041]S2. After the raw material plate pretreatment is completed, it enters the unipolar plate forming process, including that the raw material plate is transported to the position of the forming machine through the automatic conveying system, the manipulator grabs the raw material plate and sends it to the forming mold, and the forming machine is started. After applying pressure, The thickness of the raw material plate is compressed to 0.5-5mm, and at the same time, the required flow field is pressed on the upper surface or the upper and lower surfaces of the raw material plate, and the raw ...

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...
