Description

Background of the invention(a) Field of the invention

[0001] The present invention relates to a fuel cell and in particular to a manufacturing device and a manufacturing method for a fuel cell component, which continuously unwinds (e.g., from a roll) a lower sub-seal (e.g., lower sub-seal) and an upper sub-seal (e.g., upper sub-seal) and binds them to an MEA which is provided in an unwinding state (e.g., unwinding from a roll). (b) Description of related technology

[0002] A membrane electrode assembly (MEA), which is a major component, is arranged on the innermost side of a polymer electrolyte fuel cell, and catalyst layers for an anode and a cathode are arranged on both sides of an electrolyte membrane that forms a center (between them), which is called a 3-layer membrane electrode assembly.

[0003] Furthermore, a condition (e.g., a device) in which gas diffusion layers (GDLs) are also layered outside the catalyst layers is called a 5-layer membrane electrode arrangement.

[0004] The membrane electrode assembly further comprises: a bottom seal, separate from the polymer electrolyte membrane, and the catalyst layers (electrodes) arranged on both sides of the polymer electrolyte membrane. The bottom seal facilitates handling of the membrane electrode assembly and is thicker (e.g., has a greater thickness) than the catalyst layers (electrodes), specifically at the edges of both sides of the polymer electrolyte membrane. Generally, polymer films such as inert PE and PEN are used.

[0005] If a partition plate, which has flow fields for supplying fuel to the outside(s) of the gas diffusion layers of the membrane electrode arrangement, is designed as described above, and a (process of) removal of water generated in a reaction is layered, it becomes a (single) unit cell, and if a plurality of unit cells are stacked (e.g., connected in series in a stack), it becomes a fuel cell stack (e.g., a fuel cell stack) with a desiredly adapted size.

[0006] Two methods exist for manufacturing membrane electrode arrays: one involves producing a 5-layer membrane electrode array using a CCG process (catalyst-coated-on-GDL process), which applies catalyst layers for an anode and a cathode directly to the gas diffusion layer and bonds them (together) to a polymer electrolyte membrane. In contrast, there is a method for producing a 3-layer membrane electrode array using a CCM process (catalyst-coated-on-membrane process), which applies or attaches catalyst layers for an anode and a cathode directly to a polymer electrolyte membrane.

[0007] In accordance with the CCS process (catalyst-coated-on-substrate process) or the CCG process (catalyst-coated-on-GDL process), which apply catalyst layers directly to a gas diffusion layer, catalyst layers for an anode and a cathode are applied directly to a gas diffusion layer, and then the catalyst layer and a polymer electrolyte membrane are bonded by thermal pressure bonding, thereby producing a 5-layer membrane electrode arrangement.

[0008] In contrast, according to the CCM process (catalyst-coated-on-membrane process), which applies catalyst layers directly to a polymer electrolyte membrane, it is possible to produce a 3-layer membrane electrode arrangement by directly applying catalyst layers for an anode and a cathode to a polymer electrolyte membrane, but there is (in this case) a need for a specific process of layering a gas diffusion layer onto the catalyst layers and binding them by pressure.

[0009] This means that the CCM process requires a process of binding a gas diffusion layer to catalyst layers when a 3-layer membrane electrode assembly is introduced into a stack manufacturing process (e.g., stack manufacturing process) which stacks a plurality of cells by using an automated device after the 3-layer membrane electrode assembly has been manufactured, in which catalyst layers are applied directly to a membrane electrode assembly, i.e., a polymer electrolyte membrane.

[0010] Furthermore, the following can be applied: a rolling process of loading (e.g. applying) an MEA onto a lower sub-sealing film, attaching an upper sub-sealing film to it and pressing this, but performance may be reduced by a process of loading a thin electrode membrane.

[0011] Furthermore, a rolling process of applying and pressing a lower sub-sealing film and an upper sub-sealing film to the top and bottom of an electrode membrane film can be used, but the loss of input (material) of an electrolyte membrane is large, although productivity is high, therefore the manufacturing costs may be increased.

[0012] The description of related technology has been set out to help understand the background of the present invention, and it may include items from related technology that are known to the person skilled in the art.

[0018] The MEA can comprise: a polymer electrolyte membrane and electrode membranes, which are formed on central sections of one (e.g. upper) surface and another (e.g. opposite or lower) surface of the (polymer) electrolyte membrane, and the protective film can be arranged on the outer (e.g. lower) surface of one of the electrode membranes.

[0019] The electrolyte membrane roll cutter can cut a preset area of ​​the (e.g., lateral) edge of the electrolyte membrane, excluding the electrode membrane.

[0020] The upper sub-seal can be pressed against the outer surface of the (e.g., lateral) edge of one of the electrode membranes and against a (e.g., predominantly upper) surface of the electrolyte membrane, and the lower sub-seal can be pressed against the outer surface (e.g., of a lateral edge) of another of the electrode membranes, against another (e.g., predominantly lower) surface of the electrolyte membrane, and against the upper sub-seal.

[0021] The device may further include a feed conveyor belt which is arranged behind (e.g. in relation to a flow direction of a process) the electrolyte membrane roll cutter and moves the structure panel from the MEA unwinder to the MEA rewinder.

[0022] Roll cutters for cutting (e.g. in a roll-and-cut process) the upper sub-seal and the lower sub-seal into preset shapes can each be arranged behind (e.g. in relation to a flow direction of a process) the upper sub-seal unwinder and the lower sub-seal unwinder.

[0023] Furthermore, in other words, according to another embodiment of the present invention, a manufacturing process for a fuel cell component comprises: feeding a structural panel in which an MEA is formed on a protective film, cutting (e.g. in a roll-and-cut process) a preset area of ​​the edge of the electrolyte membrane of the MEA and removing any cutting waste, applying an upper sub-seal to the electrolyte membrane on a side opposite the protective film and pressing the upper sub-seal at a preset temperature, removing the protective film after the upper sub-seal has been pressed, applying a lower sub-seal after the protective film has been removed so that it corresponds to the upper sub-seal, and pressing the lower sub-seal at a preset temperature.

[0024] When feeding a structural panel, the structural panel, which is wound on a roll form on an MEA unwinder, can be unwound and fed in.

[0025] The upper sub-seal and the lower sub-seal can be pressed using a hot roller.

[0026] To attach the upper sub-seal and the lower sub-seal to the electrolyte membrane, the upper sub-seal, which is wound in a roll form on an upper sub-seal unwinder, can be unwound and fed in, and the lower sub-seal, which is wound in a roll form on a lower sub-seal unwinder, can be unwound and fed in.

[0027] The upper sub-seal, which is fed by the upper sub-seal unwinder, and the lower sub-seal, which is fed by the lower sub-seal unwinder, can each be cut into preset shapes using a roll cutter.

[0028] An edge area of ​​the electrolyte membrane can be cut using a roll cutter, and waste from the electrolyte membrane can be wound up using a waste winder and stored in a roll form.

[0029] The MEA can include: a polymer electrolyte membrane and electrode membranes formed on central sections of one surface and another surface of the (polymer) electrolyte membrane, and the protective film can be arranged on the outer surface of one of the electrode membranes.

[0030] The upper sub-seal can be pressed against the outer surface of the edge of one of the electrode membranes and against a surface of the electrolyte membrane, and the lower sub-seal can be pressed against the outer surface of another of the electrode membranes, against another surface of the electrolyte membrane and against the upper sub-seal.

[0031] In embodiments of the present invention, an MEA structural panel is continuously supplied in a state in which an electrode membrane (e.g., a membrane electrode assembly, MEA) is (already) attached to a protective film, thus saving a process of loading (e.g., applying) an MEA, and accordingly, productivity can be increased.

[0032] Furthermore, the loss of waste formed from an electrolyte membrane is minimized and recovered, thus reducing manufacturing costs, and manufacturing efficiency can be improved by bonding an MEA to an upper sub-seal and to a lower sub-seal using a roll-to-roll process.

The electrolyte membrane 105 is cut by the electrolyte membrane roll cutter 106, separated by the waste winder 116, and recovered in a roll form.

[0065] In (step) S610, the electrolyte membrane roll cutter 106 cuts a preset area of ​​the edge of the electrolyte membrane 105 from the structure panel, and the waste winder 116 separates the cut waste from the structure panel by pulling on it and stores it in a roll form.

[0067] Furthermore, in step S630, the first hot roller 130 presses the upper sub-seal 125 onto the upper surface of the structure panel. The upper sub-seal 125 is thereby attached to the edge of a surface of the electrode membrane 100 and to the upper surface of the electrolyte membrane 105.

[0068] In (step) S640, the protective film winder 112 separates the protective film 110, which is attached to the lower section of the structure panel, by pulling on it and stores it in a roll form.
