In the die cavity of sealing mold.
Before uv-curable glue being injected as a preferred technical solution, in the die cavity of seal mold, to cavity surface
Spray one layer of releasing agent.Releasing agent is adhered to each other with plastic seal mold after capable of avoiding ultra-violet curing gum forming and is difficult to
Demoulding.
The time of the solidification process is 5-10s as a preferred technical solution,.
Compared with prior art, the utility model has the characteristics that：
1) utilize uv-curable glue (UV optic-solidified adhesives) under the irradiation of ultraviolet light can quick-setting performance, will be traditional
Heat-curable glue replace with uv-curable glue, prepare sealing element, and directly sealing element is molded on pole plate, not only have good
Sealing performance, and will not have an adverse effect to MEA, pole plate, securely and reliably；
2) uv-curable glue without heating, only need ultraviolet light 5-10s can curing molding, be far below thermoset rubber
The molding time of 3-5min substantially reduces the preparation time of sealing element, solves existing fuel battery sealing piece because using liquid
The problems such as efficiency present in state rubber injection or individual seals attachment molding is low and difficult to install, it is safe and efficient；
