Abstract
The utility model relates to a metal sheet fuel cell stack with high integration degree. The fuel cell stack comprises a fuel cell stack main body and two fixed end plates which are respectively fastened at two sides of the fuel cell stack main body. The fuel cell stack is characterized in that a floating end plate is arranged between any one fixed end plate and the fuel cell stack main body; a spring is fixed on the side surface of the floating end plate. The fuel cell stack has the technical-economic effects that the external dimension of the fuel cell stack is fixed, so that the productization application, transportation and disassembling/assembling of the fuel cell stack can be conveniently carried out; the whole fuel cell stack is high in integration degree, so that the volumetric specific power of the fuel cell stack can be improved; the encapsulation plates on the side surfaces of the fuel cell stack have the fastening functions, i.e., the fuel cell stack is difficult to deform because having a large overall cross-sectional area, so that the assembling force can be uniformly distributed on the fuel cell stack; the interior of the fuel cell stack is compensated by the spring, so that when the assembling force of the fuel cell stack is changed, the actual assembling force in the fuel cell stack is more approximate to a design assembling force and the attenuation of the assembling force of the fuel cell stack can be delayed; the end plates which can float freely are adopted, so that the effective delivery of the assembling force in the fuel cell stack is ensured. As a result, the fuel cell stack is simple and convenient to assemble, thereby being beneficial to improvement on the production efficiency.
Description
Technical field
The utility model belongs to fuel cell technology field, relates in particular to film fuel cell electric piling.
Background technology
Current fuel cell pile at more piece list pond heap poststack, is exerted pressure to pile by both sides end plate conventionally.Pressure method is divided into two classes substantially: a class is fastening at the peripheral screw rod that uses of pile, and a class is fastening by bundling belt.
The defect of screw is: 1) increased pile sectional area, and then increased pile volume, reduced volumetric specific power; 2) multiple screw rods need to be distinguished reinforcing, cause assembling process loaded down with trivial details, and are difficult to ensure the consistency of power between screw rod, cause pile unbalance stress; 3) factors such as screw rod is exposed in pile periphery,, pile protection attractive in appearance in electric safety, product are considered also to need further processing, and productionization extent is lower.
Strap-on defect is: 1) consider that air, fuel and cooling agent are imported and exported and electric current output positive and negative electrode, patrol and examine the interference problem of outlet etc., the width of bundling belt is difficult to ensure, deformation easily occurs and cause actual assembled power lower than design load; 2) bundling belt thickens and can cause pile assembly operation difficulty, and the precision of assembling force is difficult to ensure; 3) bundling belt chamfering place realizability easy and that end plate friction causes assembling force cannot effectively be delivered to the servo-actuated compensation such as pile body, spring is affected.
Chinese patent CN2388714Y discloses a kind of structure of Integral packaged proton exchanging film fuel cell.The proton exchange film fuel cell electric piling that this patent relates to, takes overall package structure, comprises end cap (similar end plate), box part (surrounding encapsulation one surrounds box-like), pile
And fastener composition.But it exists two large weak points:
This patent relates to the indemnifying measure that pile inside does not have assembling force to decline, can be in the time that pile high-temperature operation, cold-starting and long-play back part self decays, pile assembling force generation acute variation, occurs significantly to decline in time, causes each parts Contact state variation internal resistance to increase; Cause pile to leak outside and the string leakage quantity increase of each chamber, fail safe reduces, and gas effciency reduces; Finally cause electric pile structure design failure, the lost of life.
The box part that this patent relates to is that the package board one of surrounding surrounds, and therefore this structure will be very difficult in the time of pile assembling and repair demolition.In the time of assembling, if first by the compression of pile main body, cannot walk around pressue device the integrated box-like part of surrounding encapsulation will be enclosed within to pile outside; If pressurizeed again after first box part being enclosed within to pile outside, be difficult to ensure that pile parts are not offset after pressurized, and then impact aligns and insulate.
Utility model content
For overcoming defect of the prior art, the utility model proposes following technical scheme: a kind of high integration metallic plate fuel cell pile, comprise pile main body and be fastened on each fixed charge method end plate of these pile main body both sides, its feature is: among two fixed charge method end plates, between any and pile main body, be provided with unsteady end plate, the side of this unsteady end plate is fixed with spring.The quantity of the fixing spring in end plate side of floating is 16.
The high integration metallic plate fuel cell pile that has adopted above technical scheme, can reach following technique effect:
Pile outside dimension is fixed, and facilitates commercialization application and transport, dismounting.
Whole pile integrated level is high, contributes to promote the volumetric specific power of pile.
Side package board plays the role of fastening, and overall sectional is long-pending is difficult for occurring very greatly self
Deformation, is conducive to maintain the overall assembling force of pile, and assembling force is uniformly distributed on pile.
Pile is inner to be beneficial in the time that the assembling force of pile changes by spring-compensating, makes the actual assembled power of pile inside more approach design and assembly power, also can delay the decay of pile assembling force simultaneously.
Pile is inner exist one can free floating end plate, can guarantee effective transmission of the inner assembling force of pile.
The assembling process of pile is simple and convenient, is conducive to enhance productivity.

Embodiment
Below in conjunction with accompanying drawing, the utility model is done to further concrete detailed description in detail:
As can be seen from Figure 1, the internal structure of a kind of high integration metallic plate of the utility model fuel cell pile comprises pile main body 1, the in-built 160 single ponds of joint, 2 collector plate in present case.The both sides outermost of pile main body 1 has respectively a fixed charge method end plate 2 and 3.Between between pile main body 1 and either side fixed charge method end plate 2 or 3, be provided with a unsteady end plate 4.
Fig. 2 expresses in present case and on the end plate 4 that floats, to be placed with quantity is the spring 5 of 16.Spring model can adopt SWL40-40.
Outside two end plates 2 and 3 and package board fix, the package board of pile surrounding is formed by the flat plate splicing of 4 directions, package board can adopt thick 304 corrosion resistant plates of 0.2mm.
After pile assembling, assembling force is provided by the package board of whole side; And can free floating at the free end plate of pile inside.Under different pile conditions, when the inner assembling force of pile changes, the relative position of external dimensions and external endplate does not change; And in pile inside, spring affords redress to assembling force by flexible, with the variation of spring, occurrence positions changes the end plate that floats.
