[0077] Example 1
[0078] 1) The two sides of the frame laminate material used are parallel, and the thickness of the supporting film, the first adhesive layer, the frame film, the second adhesive layer and the protective film are 100μm, 10μm, 20μm, 10μm, 20μm, respectively. The first adhesive layer and the second adhesive layer are adhesives. Punching the frame laminate so that the die is perpendicular to the frame laminate, punching the active area from one side of the protective film to the side of the supporting film, the punching depth is 80-140μm, the punching area is rectangular, and the size is 50x50mm. Two edges of the active area are parallel to both sides of the frame laminate material, and the distance is both 25mm. After the blanking is completed, keep the active area of the frame stack not peeling off;
[0079] 2) Peel off the first protective film of the Nafion212 film laminate with a width of 100mm from DuPont to keep the second protective film and the Nafon212 ...

[0089] Example 2
[0090] 1) The two sides of the frame laminate material used are parallel, and the thickness of the supporting film, the first adhesive layer, the frame film, the second adhesive layer and the protective film are respectively 150μm, 10μm, 20μm, 10μm, 20μm, The first adhesive layer and the second adhesive layer are adhesives. The adhesive of the first adhesive layer is in a special state. It will not adhere after contacting the polymer ion exchange membrane. It will also be peeled off. No part or all of the adhesive is attached to the polymer ion exchange membrane. The frame laminate is punched, so that the knife edge of the die is perpendicular to the laminate plane, and the active area is punched from the side of the protective film to the side of the support film. The punching depth is 80-180μm, and the punching area is rectangular, and the size is 50x50mm, two edges of the active area are parallel to both sides of the frame laminate material, and the distanc...
