Embodiment Construction

[0035] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0036] The bipolar plate is a core component of the fuel cell. It is composed of a plate and a flow field, including a gas inlet, a gas reaction zone, and a gas outlet. Because in the stack, adjacent battery cells need to share electrode plates as the anode and cathode of two adjacent battery cells, the electrode plates are usually ca...

Abstract

The invention discloses a manufacturing method for a bipolar plate of a fuel cell. The manufacturing method is characterized by being implemented in virtue of a 3D printing apparatus. The 3D printingapparatus comprises a feeding mechanism, a finished product mechanism and a laser head, wherein the laser head is arranged over the finished product mechanism; pole plates of the bipolar plate are arranged on the finished product mechanism; raw materials for manufacturing of the bipolar plate are put into the feeding mechanism, the feeding mechanism conveys the raw materials of the bipolar plate to the single pole plates on the finished product mechanism, and a raw material layer with a preset thickness is formed; and based on a preset structure of the bipolar plate, the raw material layer with the preset thickness is sintered by using the laser head so as to form the bipolar plate. According to embodiments of the invention, a mold is not needed, so the development cost of the bipolar plate is reduced, a development period is short, one-shot forming of the bipolar plate is realized, and development needs for bonding technology are reduced.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of fuel cells, and in particular to a method for manufacturing a fuel cell bipolar plate. Background technique [0002] As fuel cell technology matures, as a zero-pollution, high-efficiency power generation device that directly converts chemical energy into electrical energy, it has been increasingly used in communication base stations, vehicle power, distributed power sources and other fields. With the expansion of more application areas, more demands have also arisen. [0003] The core component of the fuel cell membrane electrode is a sheet structure. In order to smoothly enter and discharge the reactants of the fuel cell, as well as to stably control the temperature of the fuel cell and output stable electric energy, bipolar plates are used in high-power multi-cell fuel cells to realize the stacking of polar plates and membrane electrodes. [0004] Among them, the bipolar plate is at t...
