Embodiment Construction

[0022] As shown in the figure: the production steps are as follows:

[0023] ①. First process the carbon bipolar plate body 1 in the traditional way, and the carbon bipolar plate body 1 is plate-shaped. And a processing area is reserved around the carbon bipolar plate body 1 for setting a sealing layer or contacting with the gasket during installation. The thickness of the carbon bipolar plate body 1 is 1 mm or 4 mm or 8 mm or 10 mm or 12 mm or 15 mm, that is, it can be controlled between 1 mm and 15 mm.

[0024] 2. Place the carbon bipolar plate body 1 processed in the previous step in the mold groove 2, and a tooling hole 3 is provided on the side of the mold groove 2. The diameter of the tooling hole 3 is 0.5 mm or 1 mm or 2 mm or 3 mm or 4 mm or 5 mm, that is, between 0.5 mm and 5 mm. For convenience, tooling holes 3 can be provided on each side of the mold groove 2, and drilling can be selected according to needs.

[0025] ③. Use a drilling machine to drill the side of...

Abstract

A belt inspect flex fuel cell carbon double pole plate processing method, the step as follows: process carbon double pole board main body, reserve working area in periphery of the plate; put the carbon double pole board main body in the mold trough equipped with fitting holeat the side of the trough; Drill the carbon double pole board main body side at fitting hole using drilling machine to work out inspect lead mounting hole; put one end of the lead into the mounting hole; thread the lead through the mounting hole and pressure range is controlled in the range of0.1Mp-5Mp or fill the fixed inspect lead containing rubber carbon.

Description

technical field [0001] The invention relates to a processing method of a fuel cell component, in particular to a processing method of a fuel cell carbon bipolar plate with an inspection conductive wire. Background technique [0002] Fuel cells have the advantages of high energy conversion efficiency, environmental friendliness, low temperature operation and high specific power, so they can be used not only to build power stations, but also to mobile power sources, such as laptops, mobile phones, PDAs, mobile radars, mobile Communication equipment, electric motorcycles, electric cars, etc. The existing fuel cell structure is a bipolar plate arranged at intervals. The bipolar plate is the core component of the fuel cell, and it is the place where the fuel and the oxidant undergo electrochemical reactions to generate electric energy. Membrane electrodes are arranged between adjacent bipolar plates. A sealing layer is provided on the periphery of the adjacent bipolar plates, an...
