Embodiment 1

[0020] A tooling tool for processing a new type of graphite carbon plate for proton exchange membrane fuel cells. It includes a vacuum chuck bottom plate 1 and a vacuum chuck panel 2. The four corners of the vacuum chuck bottom plate 1 are provided with four special positioning pins 4 for positioning the vacuum chuck panel 2. The front side of the suction cup panel is provided with a runner groove I5, the reverse side is provided with a runner groove Ⅱ6, and two pneumatic connectors 3 are provided on both sides. One head of the pneumatic connector 3 communicates with the front runner groove I5-1 of the vacuum suction cup panel, and the other head It communicates with runner groove II6 on the reverse side. The function of the vacuum chuck bottom plate 1 is to connect and fix with the machine tool, while maintaining the level and flatness of the machining equipment to ensure the accuracy of the graphite carbon plate 7 processing; the function of the vacuum chuck plate 2 is to adso...

Embodiment 2

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

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 the production of a novel graphite carbon plate of a proton exchange membrane fuel cell. Background technique [0002] Fuel cell is a continuous power generation device that can convert chemical energy in fuel and oxidant into electrical energy through electrochemical reaction. Among them, the graphitic carbon plate plays the role of a conductive separator that supports, collects, separates the oxidant and the reducing agent in the fuel cell, and guides the oxidant and the reducing agent to flow on the electrode surface in the battery. [0003] Too high cost is the main factor that is currently difficult to commercialize proton exchange membrane fuel cells. Among them, in the process of producing hydrogen plates and air plates from related graphite carbon plates, the graphite material is relatively brittle, and it is difficult to process the flow field, resulting ...
