Embodiment 1

[0020] A processing tooling for a new type of graphite carbon plate of a proton exchange membrane fuel cell, comprising a vacuum chuck base plate 1 and a vacuum chuck panel 2, four corners of the vacuum chuck base plate 1 are provided with four special positioning pins 4 for positioning the vacuum chuck panel 2, vacuum The front of the suction cup panel is provided with flow channel groove Ⅰ5, the reverse side is provided with flow channel groove Ⅱ6, and two sides are provided with two pneumatic joints 3, one head of the pneumatic joint 3 communicates with the front flow channel groove Ⅰ5-1 of the vacuum suction cup panel, and the other head It communicates with the reverse side with runner groove II6. The role of the vacuum suction cup bottom plate 1 is to connect and fix the machine tool, and at the same time keep it level and flat with the machining equipment, so as to ensure the accuracy of the graphite carbon plate 7 during processing; The surface is sealed flat. The gra...

Embodiment 2

[0028] Proton exchange membrane fuel cell generator graphite carbon plate production and processing tooling is composed of vacuum suction cup base plate 1, vacuum suction cup panel 2, 1 / 8" pneumatic joint 3, special positioning pin 4, etc. The size is 1124.8mm * 58 mm *3mm graphite carbon plate processing ( figure 1 ). First, fix the base plate of the vacuum suction cup on the processing table to ensure that the base plate of the suction cup is horizontal and vertical to the processing table. Then place the carbon plate on the vacuum suction cup panel, and the special positioning pin will determine the processing position of the carbon plate. The front of the vacuum pad panel is shown ( Figure 4 ) Runner groove The size of the runner groove I5 is 186mm*61mm*3mm, the middle hole is ?4, and the height of the protruding groove platform is 3mm. The angle of intersection surface of runner groove is 15°. In this way, the effective area of ​​the carbon plate and the panel can...

Abstract

The invention relates to a novel processing tool for a graphite carbon plate of a proton exchange membrane fuel cell. The novel processing tool comprises a vacuum sucker bottom plate (1) and a vacuum sucker panel (2). Four corners of the vacuum sucker bottom plate (1) are provided with four special positioning pins (4) used for positioning the vacuum sucker panel (2), the front face of the vacuum sucker panel is provided with a channel slot I5, the back face of the vacuum sucker panel is provided with a channel slot II6, and two sides of the vacuum sucker panel are provided with two pneumatic connectors (3). The processing tool is characterized in that a graphite carbon plate to be processed is adsorbed to be tightly attached to the vacuum sucker panel (2) and is positioned by the special positioning pins (4). A hydrogen plate and an air plate are processed on one vacuum sucker. During processing, the hydrogen plate and the air plate are constrained mutually, and the productivity can be improved. Meanwhile, the vacuum sucker is designed to separate channels for processing the hydrogen plate and the air plate, and thus gas leakage of different channels in processing can be avoided.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a processing tool for producing a novel graphite carbon plate of a proton exchange membrane fuel cell. Background technique [0002] A fuel cell is a continuous power generation device that converts chemical energy in fuel and oxidant into electrical energy through electrochemical reactions. Among them, the graphite carbon plate plays the role of a conductive separator in the fuel cell that supports, collects, separates the oxidant and the reducing agent, and guides the flow of the oxidizing agent and the reducing agent on the electrode surface of the battery. [0003] The high cost is the main reason why proton exchange membrane fuel cells are currently difficult to commercialize. In the process of producing hydrogen plates and air plates with related graphite carbon plates, due to the relatively brittle graphite material, it is difficult to process the flow field, resulting in...
