    However, the conventional example of Patent Document 1 requires an operation of providing an intermediate adapter insertion hole in all fuel cell components and an operation of engaging the insertion hole with the intermediate adapter when the fuel cell components are stacked. In addition, there is a problem of restricting the space required for the fuel cell by providing the insertion hole.

  Further, in the conventional example of Patent Document 2, single cells can be obtained continuously, but there is a problem in that a separate stacking step on the fuel cell stack is required and the manufacturing cost is increased.

  Accordingly, the present invention has been made in view of the above problems, and an object thereof is to provide a method and apparatus for manufacturing a fuel cell stack that can reduce the manufacturing cost.

  The present invention includes a movable stage that can hold a cell in which the electrolyte membrane is sandwiched between separators in a stacked state, and supplies the electrolyte membrane to a supply position spaced from the separator of the stacked cell, The separator is inserted into the charging position separated from the separator, and the separator is pressed against the separator of the cell stacked on the movable base by the stroke exceeding the electrolyte membrane supply position from the charging position, and these are integrated with the existing stacked cell. The cells were sequentially stacked on the movable table.

Thus, since the cells are sequentially stacked on the movable base, single cells can be formed and stacked with the same stroke, a positioning jig is unnecessary, and a fuel cell stack can be manufactured efficiently and inexpensively.

  Hereinafter, a method and apparatus for manufacturing a fuel cell stack according to the present invention will be described based on an embodiment.

FIG. 4 is a sectional view of another embodiment of the manufacturing apparatus, and FIG. 5 is a plan view of the manufacturing apparatus.

  In FIG. 1, the fuel cell stack manufacturing apparatus includes an upper movable table 6 provided on a frame 5 so as to be movable up and down, a lower movable table 7 disposed on the frame 5 so as to be movable up and down facing the upper movable table 6, A laminating apparatus 1 comprising a holding frame 8 disposed so as to cover the periphery of the lower movable table 7, an electrolyte membrane supplying apparatus 2 that supplies an electrolyte film 9 to the laminating apparatus 1, and a separator assembly 10 in the laminating apparatus 1 And a separator supply device 3 for supplying the separator.

  The upper movable table 6 of the laminating apparatus 1 is configured to move up and down so that the supplied separator assembly 10 is stacked on the lower movable table 8 together with the electrolyte membrane 9 supplied separately. The upper movable table 6 includes a suction chuck (not shown) capable of gripping the separator assembly 10 supplied from the supply device 3 and is moved downward from the raised initial position by an actuator such as a cylinder (not shown). It can be moved up and down.

  Specifically, as will be described later, the separator assembly 10 is pressed from the initial position against the fuel cell constituent member 4 already stacked on the lower movable base 7 and the electrolyte membrane 9 placed thereon. Further, the separator assembly 10 held together with the separator assembly 10 is lowered to an operation position where the separator assembly 10 can be pushed into the holding frame 8, and then the suction chuck is released to leave the separator assembly 10 in the holding frame 8 to the initial position. It is configured to rise. The stroke from the initial position to the operating position is the same as the thickness of the separator assembly 10 and the electrolyte membrane 9, and the fuel cell component 4 stacked on the separator assembly 10 and the lower movable base 7 at the initial position. The length is set by adding both gap dimensions to the electrolyte membrane 9.

  The lower movable table 7 of the stacking apparatus 1 holds the fuel cell components 4 that are sequentially stacked in a stacked state, and is configured to move up and down relative to the frame 5 by an actuator such as a cylinder (not shown). doing. Around the lower movable base 7, the fuel cell component 4 stacked on the lower movable base 7 is guided and fixed to the frame 5 so that the fuel cell component 4 does not fall down or shift. A frame 8 is provided. When a predetermined number of fuel cell components 4 are stacked in the holding frame 8, the stacking fuel cell components 4 in the holding frame 8 are fastened by stud bolts with end plates (not shown) arranged at both ends. Raise it and take it out.

  The lower movable table 7 is raised to a forward position where the upper surface of the separator assembly 10 stacked from the initial position is brought into contact with the arranged electrolyte membrane 9 to apply tension to the electrolyte membrane 9, and the upper movable table 7 is moved upward. 6 is moved in conjunction with the lowering operation to the lowering position by the stacking operation, and the lowering position is set as a new initial position. That is, every time the fuel cell component 4 is stacked, the fuel cell components 4 are sequentially moved downward to a new initial position. The new initial position after the stacking operation is a position lowered by the thickness dimension of the electrolyte membrane 9 and the separator assembly 10 to be stacked as compared with the initial position in the previous stacking operation. By changing the initial position in this way, the initial interval between the upper surface of the separator assembly 10 and the electrolyte membrane 9 to be supplied is always constant.

  The electrolyte membrane supply device 2 rotatably supports the electrolyte membrane 9 of the roll body 9A wound in a charged state, rotates the roll body 9A in the unwinding direction, and extends into a sheet shape. The separators 10 are sequentially supplied between the upper and lower movable bases 6 and 7 of the laminating apparatus 1 while holding both sides of the electrolyte membrane 9 in the feeding direction by the transport rollers 11. The electrolyte membrane supply device 2 supported the tip end side of the electrolyte membrane 9 on the vertical movable bases 6 and 7 every time when the stacking operation of the vertical movable bases 6 and 7 was completed and the upper movable base 6 was returned to the initial position. It operates to feed between separator assemblies 10.

  As shown in FIG. 2 or FIG. 3, when the transport holes 12 are arranged on both sides of the electrolyte membrane 9, feed protrusions (not shown) provided on the outer periphery of the transport roller 11 are sequentially provided in the transport holes 12. By engaging and rotating the transport rollers 11 synchronously, the film surface of the electrolyte membrane 9 can be transported without sagging.

  As shown in FIG. 2, the electrolyte membrane 9 is easily separated from the surrounding electrolyte membrane 10 when it is stacked in the holding frame 8 by being sandwiched between separator assemblies 10 supported on the upper and lower movable bases 6 and 7. In order to facilitate punching, when the cuts 13 are formed in a frame shape at predetermined intervals, the pitch between the cuts 13 is supplied intermittently. As shown in FIG. 3, when there is no cut in the electrolyte membrane 9, it is necessary to cut and separate with a cutter or the like after being sandwiched between the separator assemblies 10 of the upper and lower movable bases 6 and 7, for example, FIG. As shown in FIG. 3, the upper movable table 6 is configured to be cut by a cutter 15 having a cutting edge around the separator assembly 10.

  Further, the stacking apparatus 1 shown in FIG. 4 includes a punching cutter 15 that surrounds the upper movable table 6 and can be lowered, and the cutter 15 is always retracted to a standby position that is raised above the upper movable table 6. The upper movable table 6 is exposed, and the separator assembly 10 held by the upper movable table 6 being lowered from the initial position is used for the electrolyte between the separator assemblies 10 stacked on the lower movable table 7. When the membrane 9 is sandwiched, it is lowered from the periphery of the upper separator assembly 10 to a cutting position where the electrolyte membrane 9 is cut, and is then raised to a standby position when the upper movable table 6 is stacked. Yes.

A nozzle that generates a carrier airflow that flows in the supply direction along the nozzle may be disposed, and the electrolyte membrane 9 may be held by the carrier airflow ejected from the nozzle and conveyed between the upper and lower movable bases 6 and 7.

  In this case, since the conveyance roller 11 or the like that directly contacts the electrolyte membrane 9 is not required, the electrolyte membrane 9 is not damaged, and the wrinkles and slack of the electrolyte membrane 9 are removed stably by the conveyance airflow. Thus, the performance of the assembled fuel cell can be stabilized. In addition, a simple apparatus configuration in which the carrier airflow is generated in the conveying direction on both sides of the electrolyte membrane 9 can be used, and an inexpensive manufacturing apparatus can be obtained. In addition, since the entire surface of the electrolyte membrane 9 can be used as the fuel cell component 4, the electrolyte membrane 9 is effectively used without requiring the large-width electrolyte membrane 9 having an extra width for the conveyance by the conveyance roller 11. can do.

  The separator supply device 3 supplies the separator assembly 10 to the upper movable table 6 of the laminating device 1, and as shown in FIG. 5, a separator conveying device 16 that conveys the separator assembly 10 to the laminating device 1; And a separator loading device 17 for loading the separator assembly 10 conveyed by the separator conveying device 16 into the laminating apparatus 1. The separator conveying device 16 conveys the separator assembly 10 sub-assembled in advance to the stacking device 1 by a sub-assembly device (not shown). The separator loading device 17 grips the supplied separator assembly 10 by the swivel arm 18, and swivels and conveys the separator assembly 10 to the loading position (below the upper movable table 6) to the stacking device 1. The operation of holding the suction chuck 6 is repeated every time the stacking operation of the stacking apparatus 1 is completed.

  As shown in FIG. 6, the separator assembly 10 put into the laminating apparatus 1 is configured by combining a separator 20 with a gas diffusion layer 21 and a sealing material 22. That is, the separator 20 is provided with gas flow paths 20A and 20B on both sides thereof, and covers the gas flow paths 20A and 20B on the respective surfaces, and joins the cathode side gas diffusion layer 21A and the anode side gas diffusion layer 21B to each gas. The sealing materials 22A and 22B are arranged around the diffusion layers 21A and 21B.

  When the gas diffusion layers 21 are bonded in advance to both surfaces of the electrolyte membrane 9 supplied to the laminating apparatus 1, the separator assembly 10 to be charged into the laminating apparatus 1 has the separator 220 gas on both surfaces. The flow paths 20A and 20B are provided, and the sealing materials 22A and 22B are joined around the area where the gas flow paths 20A and 20B are provided.

The stacking operation of the fuel cell stack is performed through the manufacturing process shown in FIG. Hereinafter, each manufacturing process of FIG. 8 will be described. When the laminating apparatus 1 is stopped, the upper movable table 6 and the lower movable table 7 are in the initial positions.

  In the first separator setting step S1, as shown in FIG. 7, the separator assembly 10 in which the gas flow path is disposed only on the upper side surface, and the gas diffusion layer 21 and the sealing material 22 are assembled on the upper surface is introduced. In the second and subsequent separator setting step S1, the separator assembly 10 in which the gas diffusion layer 21 and the sealing material 22 are assembled on the upper and lower surfaces is loaded. The inserted separator assembly 10 is held by the upper movable table 6 by a suction chuck.

  In the electrolyte membrane supply step S2, as shown in FIG. 1, the electrolyte membrane 9 is pulled out by rotating the roll body 9A wound in a roll shape by the electrolyte membrane supply device 2, and the vertical movable bases 6 and 7 are drawn by the transport roller 11. When the electrolyte membrane 9 is inserted to a predetermined position between the separator assemblies 10 held by the separator assembly 10, the rotation of the transport roller 11 is stopped and the electrolyte membrane 9 is set. In the first stacking operation, the electrolyte membrane 9 is not supplied because nothing is stacked on the lower movable table 7.

  In the electrolyte membrane tension applying step S3, the lower movable base 7 is raised to the forward movement position, and the upper surface of the separator assembly 10 stacked on the lower movable base 7 is brought into contact with the lower surface of the electrolyte membrane 9, and FIG. As shown, the electrolyte membrane 9 is pushed up. When the electrolyte membrane 9 is lifted up by the separator assembly 10, surface tension is generated in the electrolyte membrane 9 itself, so that wrinkles and sagging of the electrolyte membrane 9 are removed, and the separator assembly 10 is in a good condition. Overlaid. At the time of the first stacking operation, nothing is stacked on the lower movable table 7 and the electrolyte membrane 9 is not supplied, so this step is not executed.

  In the electrolyte sandwiching step S4, as shown in FIG. 10, the upper movable table 6 is lowered, and the separator assembly that is held by the upper movable table 6 on the upper surface of the electrolyte membrane 9 that is tensioned on the lower movable table 7 The lower surface of the solid body 10 is brought into contact, and the electrolyte membrane 9 is sandwiched between the separator assemblies 10. Since the electrolyte membrane 9 is in a state where a tension is applied, the electrolyte membrane 9 is sandwiched between the separator assemblies 10 in a state in which no wrinkles or sagging occurs in the upper and lower separator assemblies 10. At the time of the first stacking operation, nothing is stacked on the lower movable table 7 and the electrolyte membrane 9 is not supplied, so this step is not executed.

  In the electrolyte membrane punching step S5, the upper movable table 6 and the lower movable table 7 are both lowered, and a tension is applied to the electrolyte membrane 9 sandwiched between the upper and lower separator assemblies 10 in a direction crossing the membrane surface. The electrolyte membrane 9 is punched out to a predetermined size along the notch 13 provided in. When there is no cut in the film surface, the cutter 15 is lowered to the cutting position, and the electrolyte membrane 9 is cut out to a predetermined size. At the time of the first stacking operation, nothing is stacked on the lower movable table 7 and the electrolyte membrane 9 is not supplied, so this step is not executed.

  In the stacking step S6, the vertical movable bases 6 and 7 are lowered to lower the separator assembly 10 sandwiching the electrolyte membrane 9, and when the upper movable bases 6 and 7 reach the operating position as shown in FIG. Stop. When the upper movable table 6 reaches the operating position, the sandwiched electrolyte membrane 9 is inserted into the holding frame 8, and a part of the upper separator assembly 10 is inserted into the holding frame 8. The upper surface of the assembly 10 is located a predetermined distance away from the lower surface of the electrolyte membrane 9 to be supplied next time. In the holding frame 8, separator assemblies 10 that are sequentially stacked on the lower movable table 7 are stacked with the electrolyte membrane 9 interposed therebetween. At the time of the first stacking operation, only the separator assembly 10 is sandwiched between the upper and lower movable tables 6 and 7, and the separator assembly 10 is held together with the lower movable table 7 by the lowering of the upper movable table 6 to the operating position. It is inserted into the frame 8.

  In the upper separator holding release step S7, the suction chuck of the upper movable table 6 is released, and in the upper movable table initial position return step S8, the upper movable table 6 is raised to the initial position as shown in FIG. The separator assembly 10 held by the upper movable table 6 is maintained in a state of being stacked on the lower movable table 7 while being inserted into the holding frame 8.

  In this determination step S9, it is determined whether or not the predetermined number of cells are stacked on the lower movable table 7. If the predetermined number of cells has not yet been reached, steps S1 to S8 are repeated, and the lower movable table 7 is repeated. Lamination by the laminating apparatus 1 is completed when a predetermined number of cells are laminated thereon.

  As described above, in the fuel cell stack manufacturing apparatus, the electrolyte membrane 9 can be assembled and held in the separator assembly 10 in a good state by the steps S1 to S5, and the steps S6 to S7. At the same time, stacking them can be performed, so that a fuel cell stack can be manufactured with a simple manufacturing method at low cost and with stable quality.

  As a result, the fuel cell stack has been expensive because it has been manufactured with labor and excessive quality control, but it can make significant cost reductions and can be mass produced. .
