The opposite third end of 200 platform of power machine and the 4th end.Second end plate 102 is placed in the first frock clamp 210 and the second tooling folder
Region between tool 220, the first frock clamp 210 and the second frock clamp 220 can limit fuel cell pile 100
Position, it is ensured that fuel cell power generation body 105 can be just installed in place from top to bottom, then by floating support body 106, insulating spacer
103, the second electric current export body 104b, fuel cell power generation body 105, the first electric current export body 104a, insulating spacer 103 and the
The successively installation stacking in order of end plate 101.Cracking pressure machine 200 makes press machine 200 enter compression travel to fuel cell electricity
Heap 100 is slowly compressed, and compression speed controls between 0.5mm/min-5mm/min, the first packaging part 111 or the second encapsulation
The connecting portion of part 112 reaches when being correspondingly connected with position of first end plate 101, and assembling force is no more than within ± the 5% of design value
It is reasonable.If assembling force is more than the 5% of design value, the number of plies that should reduce fuel cell power generation body 105 makes up to aforementioned conjunction
Reason value.If assembling force be lower than design value 5%, should increase fuel cell power generation body 105 the number of plies make up to it is aforementioned rationally
Value.The connecting portion of first packaging part 111 or the second packaging part 112 reach first end plate 101 be correspondingly connected with position after, use
Fastener 113 is by the first packaging part 111 and the connection with first end plate 101 and the second end plate 102 respectively of the second packaging part 112.
Finally the first frock clamp 210 and the second frock clamp 220 are removed, operating pressure machine 200 makes it into upward stroke, i.e., in fact
Now it is detached from fuel cell pile 100.By the way that the first packaging part 111 and the first frock clamp 210 are fitted together, and will
Second packaging part 112 and the second frock clamp 220 are fitted together and then are compressed to fuel cell pile 100, compare appearance
Easily realize the first packaging part 111 and the contraposition of first end plate 101 and the contraposition of the second packaging part 112 and the second end plate 102, together
When ensure that the first packaging part 111 and the second packaging part 112 are fitted closely with fuel cell power generation body 105.
It should be noted that first packaging part 111 and the second packaging part 112 of the present embodiment can not also be assembled to first
Frock clamp 210 and the second frock clamp 220.This kind the first frock clamp 210 and the second frock clamp 220 can not then open up
Slot please refers to Fig. 8.Before press machine 200 carries out compression travel, first the compressed thickness of fuel cell pile 100 is calculated
With setting scale, when press machine 200 slowly compresses fuel cell pile 100 into compression travel, the first packaging part
111 or second packaging part 112 connecting portion correspond to the corresponding position of scale and the connecting portion of first end plate 101 to it is corresponding when
Using fastener 113 by the first packaging part 111 and the second packaging part 112 company with first end plate 101 and the second end plate 102 respectively
It connects.Finally the first frock clamp 210 and the second frock clamp 220 are removed, operating pressure machine 200 makes it into upward stroke,
It realizes and is detached from fuel cell pile 100.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Within then, any modification, equivalent replacement, improvement and so on be should be included within the scope of protection of this utility model.
