Description

BACKGROUND OF THE INVENTION Field of the Invention: Apparatus for manufacturing an elastomeric cell frame for fuel cell

The present invention relates to an apparatus for manufacturing an elastic cell frame for a fuel cell, and more particularly, for a fuel cell capable of aligning the elastic frame in a static position in a preparation step for thermally fusing a sheet-shaped elastic frame made of an insert and a thermoplastic elastic material (TPE). It relates to an elastic cell frame manufacturing apparatus.

A fuel cell is a type of power generation device that converts chemical energy contained in fuel into electrical energy by reacting electrochemically within a stack. It not only supplies power to drive industrial, domestic, and vehicles, but also powers small electronic products such as portable devices. It can be used as a high-efficiency clean energy source.

Membrane-Electrode Assembly (MEA) is located at the innermost unit cell of a general fuel cell. This membrane electrode assembly has a polymer electrolyte membrane that can move hydrogen cations and this polymer electrolyte membrane. It is composed of a catalyst layer coated on both sides so that hydrogen and oxygen can react, that is, a cathode and an anode.

In addition, a pair of separating plates for supplying a reaction gas and discharging product water generated by the reaction are disposed on one side and the other side of the membrane electrode assembly, that is, the outer portion where the cathode and the anode are located. At this time, a gas diffusion layer (GDL) may be interposed between the membrane electrode assembly and the separator to diffuse or smooth the flow of reaction gas and product water.

Meanwhile, in the related art, a membrane-electrode-gasket assembly (MEGA) in which a membrane electrode assembly and a gasket are integrated was manufactured and used for the convenience of the unit cell's airtightness and lamination process.

In addition, recently, an integrated frame in which an insert in which a gas diffusion layer is bonded to a membrane electrode assembly and a gasket are integrated has been proposed.

However, in the conventional integrated frame, a frame made of plastic and an insert are joined using an adhesive. In addition, in the case of manufacturing a unit cell using a conventional integrated frame, a separate adhesive member and a sealing member were required for bonding the separation plate and the integrated frame. This process has caused an increase in material cost and production cost.

Therefore, the applicant has conducted a study to integrate the gasket with the insert by replacing the sheet-shaped elastic body frame made of thermoplastic elastomer (TPE), and accordingly, a device that can provide heat and pressure to the elastic body frame and insert at the same time is required to be thermally fused Became.

In particular, when the elastic frame is placed on the jig for thermal fusion between the insert and the elastic frame, the sheet-shaped elastic frame made of thermoplastic elastomer (TPE) causes shrinkage at the long axis due to the characteristics of the material and the shape of the insert. There was a problem that the elastic frame was not aligned correctly.

The content described above as the background art is only for understanding the background of the present invention, and should not be taken as an acknowledgment that it corresponds to the prior art already known to those of ordinary skill in the art.

Meanwhile, the insert 10 and the elastic body frame 20 have an overlapping region overlapping in a predetermined region. Preferably, the elastic body frame 20 is arranged to surround the edge of the insert 10 in the outer region of the insert 10. Thus, the overlapping region is formed in the outer peripheral region of the insert 10 and the inner peripheral region of the elastic body frame.

In particular, in the elastic body frame 20, a sealing protrusion 21 for sealing is formed in a region surrounding the reaction surface on which the insert 10 is disposed.

On the other hand, a heating unit 321 is provided on the lower surface of the upper jig 320 to provide heat and pressure while protruding in the direction of the lower jig unit 400 and directly facing the elastic frame 20.

The power unit 330 is a means for providing power to move the moving shaft 310 forward or backward, and may be implemented in various ways capable of operating the moving shaft 310. In this embodiment, the upper jig 320 is configured with a motor that moves the moving shaft 310 forward or backward, and controls the degree to which the moving shaft 310 moves forward or backward through control of whether the motor is operated and the amount of motion. A pressure for pressing the overlapping region of the insert 10 and the elastic frame 20 mounted on the lower jig unit 400 is adjusted.

The lower jig unit 400 is a unit in which the insert 10 and the elastic frame 20 are mounted for heat fusion between the insert 10 and the elastic frame 20, and is disposed on the upper surface of the base plate 100.

First, the elastic body frame 20 and the insert 10 are sequentially stacked and seated on the upper surface of the lower jig unit 400. At this time, if the elastic body frame 20 is contracted in the long axis portion due to material characteristics and shape characteristics, the elastic body frame 20 is not seated in a fixed position in the mounting groove of the lower jig unit 400. Then, as shown in FIG. 2, the elastic body frame 20 and the lower jig unit 400 are not aligned, and accordingly, the elastic body frame 20 and the insert 10 are also not aligned.

However, even if the lower jig unit 400, the elastic body frame 20, and the insert 10 are not aligned in a normal posture, the power unit 330 is operated to move the moving shaft 310 toward the lower jig unit 400. . At this time, heat is provided to the heating unit 321 provided in the upper jig 320 to heat it. When the moving shaft 310 continues to advance, the end of the guide protrusion 510, which is the alignment means 500, is in contact with the sealing protrusion 21 of the elastic frame 20 to push the long axis of the elastic frame 20 outward. Then, the elastic body frame 20, which has been contracted, is unfolded and is aligned in a fixed posture in accordance with the mounting groove formed on the upper surface of the lower jig unit 400. Accordingly, the insert 10 seated on the upper portion of the elastic body frame 20 is also aligned in a static position.

When the lower jig unit 400, the elastic body frame 20, and the insert 10 are aligned in this way, the upper jig 320 is moved forward by the continuous advance of the moving shaft 310, and the heating part 321 is moved to the insert 10 It pressurizes while providing heat to the overlapping area of the elastic body frame 20.

Then, while the elastic frame 20 is melted by the heat provided, it is integrated while being heat-sealed at the interface with the insert 10.

Meanwhile, the alignment means according to the present invention can be implemented in various forms.

When the first rod 521 and the second rod 522 are implemented in a link structure capable of lengthening and restoring, the upper jig 320 is lowered and the contact bundle 528a contacts the elastic frame 20 The contact load can be distributed as the length of the first rod 521 is shortened without applying an excessive force to the extent that the elastic frame 20 is damaged. At this time, while the length of the first rod 521 is varied, the length of the second rod 522 is also varied in correspondence with the length of the first rod 521 to maintain the posture of the alignment means 500.

And, when the heat fusion between the elastic body frame 20 and the insert 10 is completed and the upper jig 320 is moved backward, the contact bundle 528a is separated from the elastic body frame 20 and the restoring force of the first spring 526 As a result, the length of the first rod 521 is returned to its original position again, and the second rod 522 is similarly returned to its original position by the restoring force of the second spring 527 along with the alignment means 500 )'S posture returns to the initial position.
