Description

Gasket formation method and apparatus for suppressing the formation of gasket burrs {THE METHOD AND APPARATUS FOR MANUFACTURING GASKET}

The present invention relates to a gasket forming method and apparatus for suppressing the production of a gasket bur, and more particularly, to a gasket forming method for suppressing the production of a gasket burr, and suppressing the production of a gasket burr capable of forming a gasket on a separator plate. And to an apparatus.

The basic structure of a fuel cell is a structure in which a membrane-electrode assembly (MEA) in which an electrochemical reaction takes place, a gas diffusion layer (GDL), which is a porous medium for evenly dispersing the reaction gas into the membrane-electrode assembly, and a separator are alternately stacked. . Among the fuel cells, a polymer electrolyte membrane fuel cell (PEMFC) is a power generation device that directly generates electricity by an electrochemical reaction between hydrogen and oxygen.

In the polymer electrolyte membrane fuel cell, hydrogen is supplied through an anode as a fuel electrode, and oxygen is supplied to a cathode as an air electrode. Hydrogen supplied to the anode is separated into hydrogen ions and electrons by electrode layers formed on both sides of the electrolyte. Hydrogen ions pass through the electrolyte membrane to the cathode and, in the case of electrons, are collected through an external conductor through a separator to generate a current. Then, the hydrogen ions delivered to the cathode meet with oxygen in the supplied air to form water.

The separator collects and delivers the generated current, prevents direct contact between hydrogen and oxygen to prevent the risk of explosion and combustion, transport of reaction gases and products, transfer of reaction heat, transfer of reaction electrodes and catalysts, and gas diffusion layers. It serves as a structure.

In addition, the gasket of the basic structure of the fuel cell is bonded to the separator plate to become a reference for dividing each unit cell of the fuel cell stack, and at the same time independently of the hydrogen, cooling water and air flow paths formed on the surface of the separator plate. In order to ensure the function of the gasket, the method of joining the gasket to the separator and the choice of gasket material should be carefully considered in the manufacture of the fuel cell stack.

In the manufacture of fuel cell stacks, metal separators are often used to reduce the volume of the stack. In order to reduce costs, the metal separator plate generally forms a flow path by a stamping process. The separator manufactured through the stamping process performs a gasket forming process on the separator for sealing. The gasket is made of silicon-based or fluorine-based rubber having excellent elastic restoring force. In the case of the metal separator, it is impossible to form a groove for positioning the gasket and it is difficult to bond the rubber material. Hardening and bonding at the surface are generally applied. The metal separator gasket manufacturing method may be manufactured using a dispenser, but a manufacturing method using a mold having excellent quality and precision is used.

However, when the gasket is formed on the metal separator plate using a mold, the gasket may be formed in a distribution hole, a flow path, etc. of the separator plate instead of a desired formation position, and a gasket burr may be generated. There is a problem of greatly reducing the performance of a fuel cell using a separator. Therefore, there is a need for a method and apparatus for suppressing the generation of gasket burrs when forming a gasket.

Korean Unexamined Patent Publication No. 10-2015-0019810 (hereinafter referred to as Patent Document 1) proposes a gasket burr removal system and method for a fuel cell integrated with a metal separator plate. This patent discloses a gasket burr removal system for a fuel cell using a burr removing apparatus, but does not disclose a method of suppressing the generation of a gasket burr and forming a gasket.

The adhesion inhibitor may be applied to the inside of the hole and the inlet and the outlet of the hole, thereby suppressing the generation of the gasket burr at the inside, the inlet and the outlet of the hole when the gasket is formed in the separator 300. In other words, it does not affect the formation of the gasket on the separator plate, and at the same time, it is possible to suppress the occurrence of the gasket burr at an undesired position on the separator plate. Problems can be prevented.

The pin 200 or the separator 300 may be moved so that the pin 200 is inserted into at least one of the holes formed in the separator 300. For example, the separation plate 300 may be moved to fix the pin 200 at a predetermined position and to insert the pin 200 into a hole formed in the separation plate 300. On the other hand, the pin 200 may be inserted into a hole formed in the separator 300 by fixing the separator 300 at a predetermined position and moving the pin 200.

Among the holes formed in the separating plate 300, a known means may be used as a moving means for moving the pin 200 or the separating plate 300 so that the pin 200 is inserted into at least one hole, and the pin 200 or If there is a means for moving the separator 300 is not limited.

Referring to FIG. 4, the size of the pin 200 may be smaller than the size of the hole formed in the separator 300 so that the pin 200 is inserted into the hole formed in the separator 300. In addition, in order to supply the adhesion inhibitor to the inlet and outlet side of the hole formed in the separation plate 300, the size of the absorbent body 210 attached to the pin 200 is slightly larger than the size of the hole formed in the separation plate 300.

In a state where the pin 200 is inserted into the hole, the adhesion inhibitor may flow out of the moisture absorbent 210 and be supplied to the inside, the inlet, and the outlet of the hole. It may be desirable to wait for a predetermined time while the pin 200 is inserted into the hole so that the adhesion inhibitor can be sufficiently supplied to the hole. However, it may be desirable to adjust the waiting time so that the adhesion inhibitor does not flow to the position where the gaskets other than the inside, the inlet, and the outlet side of the hole should normally be formed.

By drying the adhesion inhibitor applied to the separator 300, the adhesion inhibitor can be prevented from flowing to the position where the gasket should be normally formed in addition to the desired position, and the adhesion inhibitor can be fixed and coated only at the intended position. The portion coated with the adhesion inhibitor is suppressed from adhering the gasket material by the lower surface energy, thereby preventing the occurrence of the gasket burr.

In the drying step, for example, the separation plate 300 to which the adhesion inhibitor is applied may be dried using an infrared heater. In addition, the separator 300 may be dried by contacting the separator 300 coated with the adhesive inhibitor with hot or cooling air, and may be naturally dried when an adhesive inhibitor which is rapidly evaporated due to high volatility is used.

After forming the gasket material, the gasket may be formed on the separator plate 300 by taking out the separator plate 300. However, the above-described method of forming the gasket on the separating plate is only an example for description and does not limit the method of forming the gasket.

The plurality of holes formed in the separator 300 according to an embodiment of the present invention may include at least one of a flow path, a manifold, a distribution hole, and an alignment hole. The separation plate 300 includes a flow path through which raw materials, unreacted products or reaction products are moved, a manifold through which a cooling medium such as water or cooling water, which is a reaction by-product, and a distribution hole for uniformly distributing a flow rate into the separation plate flow path, a separation plate ( Alignment hole for installing the support for alignment when manufacturing the fuel cell using the 300 may be formed. A plurality of flow paths, manifolds, distribution holes, and alignment holes may be formed in the separation plate 300.

By applying an adhesive inhibitor to the flow path, the manifold, the distribution hole or the alignment hole formed in the separation plate 300 to suppress the generation of the gasket bur, the phenomenon of reducing the performance of the fuel cell in which the separation plate 300 is used You can prevent it. In addition, even when a small amount of the gasket burr is applied to the portion to which the adhesion inhibitor is applied, the gasket burr can be easily removed, thereby reducing the cost and time required to remove the gasket burr.
