具体的，如图1、2、6所示，在质子膜单元3具有质子膜退绕机31，将质子膜90退绕出，之后运输至粘合单元4；双面胶层单元包括第一胶层单元1和第二胶层单元2，第一胶层单元1具有第一胶层退绕机11，将第一双面胶层退绕出，之后运输至粘合单元4；第二胶层单元2具有第二胶层退绕机21，将第二双面胶层退绕出，之后运输至粘合单元4；其中，第一胶层单元1具有第一模切机12，模切形成第一双面胶层的第一中心镂空部913，第二胶层单元2具有第二模切机22，模切形成第二双面胶层的第二中心镂空部923，之后，如图所示的，第一双面胶层位于质子膜上表面，第二双面胶层位于质子膜下表面，粘合单元4具有第一粘合辊41和第二粘合辊42，压辊配合形成质子膜的密封，其中，第一双面胶层的第一内胶层911朝向质子膜90的上表面901，第二双面胶层的第二内胶层921朝向质子膜90的下表面902，完成贴合。Specifically, as shown in FIGS. 1 , 2 and 6 , the proton membrane unit 3 has a proton membrane unwinding machine 31 to unwind the proton membrane 90 and then transport it to the bonding unit 4 ; the double-sided adhesive layer unit includes a first Adhesive layer unit 1 and second adhesive layer unit 2, the first adhesive layer unit 1 has a first adhesive layer unwinder 11, which unwinds the first double-sided adhesive layer, and then transports it to the adhesive unit 4; the second adhesive layer The layer unit 2 has a second adhesive layer unwinding machine 21, which unwinds the second double-sided adhesive layer, and then transports it to the adhesive unit 4; wherein, the first adhesive layer unit 1 has a first die-cutting machine 12, which is used for die-cutting.

之后，如图1、2、6所示，采用方式一进行后续催化剂层、气体扩散层、密封框层的组装：从传统意义上，可以是经过催化剂涂覆装置5，涂覆催化剂层，具体的可以是刷涂、印刷、涂覆、涂覆、刮涂、喷涂或介质转印等方式进行，涂覆可以经过一次涂布或多次涂布；然后经过气体扩散层贴合装置6，将气体扩散层压合至催化剂层表面，气体扩散层一 般为碳纸、碳纤维编织、碳布等；然后再在密封框层贴合装置7压合密封框层，利用双面胶层的外胶层进行与密封框层的粘合。Then, as shown in Figures 1, 2, and 6, the following method is used to assemble the catalyst layer, the gas diffusion layer, and the sealing frame layer: in the traditional sense, the catalyst layer can be coated through the catalyst coating device 5. Specifically, It can be carried out by brushing, printing, coating, coating, scraping, spraying or media transfer, and the coating can be coated once or multiple times; then through the gas diffusion layer laminating device 6, the The gas diffusion layer is laminated to the surface of the catalyst layer. The gas diffusion layer is generally carbon paper, carbon fiber weaving, carbon cloth, etc.; Adhesion to the sealing frame layer is performed.
还可以采用方式二，由于现有技术中已经具有市场化的气体扩散层上集合有催化剂层，则可以采用此种气体扩散层在本制备***的粘合单元4之后进行对气体扩散层与催化剂层进行粘合，此时催化剂涂覆装置5和气体扩散层贴合装置6则集合为一种贴合装置；之后再在密封框层贴合装置7进行密封框层的贴合。 Method 2 can also be used. Since there is a marketed gas diffusion layer in the prior art, a catalyst layer is assembled on it, so this kind of gas diffusion layer can be used after the bonding unit 4 of the preparation system.

当然，在后续的研发中，采用方式三，可以在气体扩散层外事先粘合有密封框层，则此时的气体扩散层贴合装置6和密封框层贴合装置7可以只需要一种贴合装置，之前的催化剂涂覆装置5可以按照方式一进行。Of course, in the follow-up research and development, the third method is adopted, and the sealing frame layer can be bonded in advance outside the gas diffusion layer, then the gas diffusion layer laminating device 6 and the sealing frame layer laminating device 7 can only need one kind of For the laminating device, the previous catalyst coating device 5 can be carried out according to the first method.
另外，采用方式四，催化剂层、气体扩散层、密封框层可能已经成为一体，则此时也只需要一种贴合装置即可完成催化剂层、气体扩散层、密封框层的贴合。In addition, in the fourth method, the catalyst layer, the gas diffusion layer, and the sealing frame layer may have been integrated. At this time, only one bonding device is needed to complete the bonding of the catalyst layer, the gas diffusion layer, and the sealing frame layer.
