Embodiment 1
[0038] The fuel cell encapsulation method includes fixing the components of the fuel cell in the fuel cell encapsulation mold in sequence, then injecting plastic into the fuel cell encapsulation mold, and releasing the mold after the plastic is cooled to form a plastic encapsulation body to obtain the fuel cell.
[0039] The above-mentioned plastics are special plastics for injection molding, including polyimide, polyethersulfone, polysulfone, polyoxymethylene, polyvinylidene fluoride or other fluorine-containing engineering plastics and other acid and alkali resistance, methanol resistance, hydrolysis resistance, excellent mechanical properties industrial plastics.
[0040] The fuel cell includes various components such as an anode current collecting plate, an anode sealing gasket, a membrane electrode, a cathode sealing gasket, and a cathode current collecting plate.
[0041] The current collector plate can be a gold-plated metal plate, a nitrided titanium plate, a graphite ...
Embodiment 2
[0045] Fuel cell packaging molds, such as figure 1 As shown, including fixed mold 1 and movable mold 2;
[0046] The fixed mold 1, such as figure 2 Shown, comprise a stripper plate 11, an upper template 13, a plurality of ( figure 2 4 in the middle) guide pillar 12, multiple ( figure 2 Among them are 2) tightly closed columns 14, multiple ( figure 2 4 in the middle) pull rod 15;
[0047] The stripping plate 11 is provided with an injection hole 111 in the middle;
[0048] One end of the plurality of guide pillars 12 is respectively fixed on the periphery of the stripper plate 11;
[0049] One end of the plurality of pull rods 15 is respectively fixed on the periphery of the stripper plate 11;
[0050]The upper template 13 is provided with a plurality of guide post sliding holes and a plurality of pull rod holes around; The other ends of the plurality of tie rods 15 respectively pass through the plurality of tie rod holes provided around the upper template 13, and th...
Embodiment 3
[0070] Fuel cell packaging mold such as Figure 7 As shown, the difference between it and the fuel cell packaging mold in the second embodiment is that there are multiple ( Figure 7 There are 3 in the middle) the upper mold groove 16 of the battery, and the upper end surface of the movable bottom plate 26 of the movable mold mold 2 is provided with a plurality of ( Figure 7 3 in the middle) battery lower mold units corresponding to multiple battery upper mold grooves 16 one-to-one;
[0071] Using the fuel cell packaging mold of the third embodiment, the flat-plate electric stack can be plastic-sealed.
[0072] The fuel cell encapsulation method of the present invention, due to the adoption of injection molding technology, reduces the volume of the encapsulated fuel cell, can significantly increase the battery energy density, and the encapsulated fuel cell has high consistency, high production efficiency, and is convenient for large-scale commercial use. chemical production...
