The reciprocating movement part 130 is moved in a reciprocating manner to a pair of guide bars 134 installed in a first incision part 114 formed in a second rotary block 113 of the rotary block 110a And a block 131.

The movable block 131 is formed with a second incision arrangement part 132 which is opened in a substantially square hole shape and the second incision arrangement part 132 is provided with the outer surface of the upper and lower squeeze rolls 30, The contact member 133 is brought into contact with the gasket sheets 10 and 20 which are moved in contact with the gasket sheet.

In this case, the contact member 133 is illustrated as being composed of the contact roll member that idles in the direction of engaging with the roll when it contacts with the gasket sheet which is moved in contact with the outer surface of the upper and lower press rolls. However, And may be made of an elastic material such as a sponge.

The outer surface of the contact member is preferably coated or coated with a pad material of a soft material so as to prevent the frictional resistance from being damaged when the contact member is brought into contact with the surface of the gasket sheet moved with the upper and lower pressing rolls.

Accordingly, the moving block 131 is moved together with the rotating block 110a toward the outer surface side of the upper and lower squeeze rolls for advancing the gasket sheets 10 and 20 during the forward movement of the first actuator 120a, The contact member 133 is moved outwardly so as to pull both sides of the gasket sheet from which the release film is removed by the release bar in a state where the contact member 133 is in contact with the surface of the gasket sheet, And is returned to the inside when the contact member 133 is separated from the gasket sheet by the return turning.

The second actuating part 140 is connected to the rod end via the moving block 131 and the connecting member 141 and the body is fixed to the second rotating block 113 of the rotating block 110a And a second actuator 140a.

The second actuator 140a is provided with an external force for reciprocating the moving block 131 together with the contact member 133 contacting or spaced from the gasket sheets 10 and 20 during forward and backward movement of the second actuator 140a, The contact member contacting the outer surface of the sheet is moved outwardly so that the gasket sheet on which the release film is peeled completely adheres to the outer surface of the roll and the movable block can be returned back for the next process.

On the other hand, at the exit side of the joining part 50 composed of the upper and lower pressing rolls 30 and 40, a thermal laminating part (upper and lower pressing rolls 30a and 40a) The electrode sheet 1 having the electrode layer formed thereon while passing through the upper and lower squeeze rolls 30 and 40 and the gasket sheets 10 and 20 formed through the electrode receiving portions are firstly joined together The electrode assembly body is secondarily bonded by heat and pressure while passing through the upper and lower thermocompression rolls 30a and 40a of the thermal laminating unit 50a to enhance the sheet integrity of the electrode assembly.

The electrode assemblies, which are manufactured while continuously passing through the joining portions and the thermal laminating portions, are cut at regular intervals to complete unit parts stacked on the fuel cells.

As shown in FIG. 7, a method for manufacturing an electrode assembly according to a preferred embodiment of the present invention includes an electrode sheet 1 having electrode layers 2 and 3 formed on both surfaces thereof, In the step of joining the gasket sheets 10, 20 formed through the portions 11, 21 to form the electrode assembly, the outer edge of the gasket sheet contacting the outer surface of the upper and lower squeeze rolls is pushed outwardly The formed gasket sheet is uniformly brought into close contact with the outer surface of the roll before it is bonded to the electrode film sheet to prevent the occurrence of the wrinkles after the adhesion.

That is, in the vicinity of the upper and lower squeeze rolls 30 and 40, which are rotated in the mutually engaging directions, the horizontal bar 101 is arranged to be parallel to the roll axis. One end of the horizontal bar 101 is rotatably assembled The rotary block 110a is brought close to the outer surface of the roll by advancing operation of the first actuator 120a provided on the fixing bracket coupled with the fixed block fixed to the horizontal bar.

At this time, the moving block 131 having the contact member 133 is disposed in the first incision part 114 formed in the rotary block 110a, so that the outer surface of the contact member is positioned on the outer surface of the upper and lower press rolls And comes into contact with the outer surfaces of the gasket sheets 10 and 20 that are wound and tangential to each other.

In this state, the moving block 131 assembled horizontally to the guide bar 134 of the first incision part 114 is moved forward by the forward movement of the second actuator 140a fixed to the rotating block 110a The gasket sheet advances to the outside of the gasket sheets 10 and 20 to provide an external force for pulling out the gasket sheet in contact with the outer surface of the upper and lower squeeze rolls without lifting.

At this time, since the contact member 133 is moved outward in contact with the surfaces of the gasket sheets 10 and 20 wound on the upper and lower squeeze rolls rotated in the mutually engaging directions, And the gasket sheet form a trajectory in an oblique direction inclined at a predetermined angle outward with respect to the roll nip portion.

The contact member 133 is made of a contact roll member that idles in a direction to engage with the roll when it is in contact with the gasket sheet that is moved in contact with the outer surface of the upper and lower squeeze rolls, So that the surface of the gasket sheet can be uniformly adhered to the surface of the lower and upper press rolls while minimizing the surface damage of the gasket sheet.

When the first actuator 120a is moved backward after the advancement of the moving block is completed, the first actuator 120a is interposed between the rotating block and the fixed bracket, and when the first actuator 120a is advanced backward, Since the rotation block 110a is rotated in the original state due to the elastic restoring force of the compressed elastic body as the gap between the rotation block and the fixing bracket becomes narrower, the other end of the rotation block 110a is moved to the outer surface of the upper and lower squeeze rolls The contact member 133 is spaced apart from the gasket sheet.

In this state, the moving block 131 is moved backward to the inside of the gasket sheets 10, 20 by the backward return operation of the second actuator 140a to separate the gasket sheets 10, The member 133 is horizontally moved inwardly away from the outer edge of the gasket sheet and returns to its original state.

At this time, since the contact members 133 spaced from the gasket sheet are moved inward from the surface of the gasket sheets 10, 20 wound on the upper and lower squeeze rolls rotated in the mutually engaging directions, The movement locus of the contact member forms an oblique locus inclined at a predetermined angle inward relative to the roll nip.

In the process of providing an external force for pulling out the gasket sheets 10, 20 contacting the contact member 133 in a state where the contact member is in contact with the gasket sheet, When the contact member contacting the gasket sheet is moved outward to provide an external force for pulling out the side edges of the gasket sheet outwardly, it is possible to prevent breakage of the gasket sheet tearing by the penetrated electrode housing portion You can do it.

On the other hand, it is preferable that the step of moving the contact member inward while the contact member is spaced from the gasket sheet is performed in a seat section through which the electrode housing section is formed.

Here, the electrode receiving portions 11 and 21 are formed in a rectangular parallelepiped shape having a short side and a long side, and the gasket sheet enters between the upper and lower squeeze rolls in the direction of the length of the short side, However, the present invention is not limited thereto, and the electrode may be joined between the upper and lower squeeze rolls in the longitudinal direction of the electrode receiving portion.

Since the number of electrode assemblies formed per unit length can be increased by advancing the gasket sheet in the direction of the short side of the electrode accommodating portion in the longitudinal direction, the gasket sheet advances in the longitudinal direction in the long side direction of the electrode accommodating portion, And high work productivity can be obtained.

An electrode film sheet 1 in which electrode layers 2 and 3 are formed while passing through roll nips of the upper and lower squeeze rolls 30 and 40 and a gasket sheet The electrode assemblies to which the first and the second thermocompression bonding rolls 10 and 20 are joined are secondarily joined together by heat and pressure while being passed through the roll nip of the upper and lower thermocompression rolls 30a and 40a for generating a pressing force, It is possible to enhance the sheet integrity of the electrode assembly to be formed.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
