Description
Technical field
The utility model is related to a kind of fuel cell piles, are filled more particularly, to a kind of bipolar plates of fuel cell pile
It sets.
Background technology
The prior art does not have special structure in bipolar plates outer ring, during fuel cell assembles, needs to pass through volume
Outer tooling is aligned bipolar plates and MEA, and packaging efficiency is low, and tooling needs additional designs, can not Fast Installation；Electricity simultaneously
It, can be since stress is excessive or discontinuity leads to the damage of MEA due to no any limiting device in heap assembling process.
Often section monocell decrement also has difference simultaneously, directly affects the consistency of whole pile, leads to individual monocell electricity occur
The phenomenon that forcing down influences overall performance and service life.
Utility model content
The purpose of this utility model is exactly to be provided a kind of with preferable to overcome the problems of the above-mentioned prior art
Consistency fuel cell pile bipolar panel assembly.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of bipolar panel assembly of fuel cell pile, including the bipolar plates and membrane electrode assembly that are superimposed, it is described
Flanging is arranged in the outer of bipolar plate body, and outer thickness is more than the thickness of bipolar plate body.
Back is arranged in the body surfaces of the bipolar plates, and the back is contacted with membrane electrode assembly.
The membrane electrode assembly includes CCM (catalyst coated membrane, catalyst coat film), CCM two
The frame of the diffusion layer and the peripheries CCM of side, the diffusion layer and facing end contact, the frame are contacted with flanging.
It is tightly connected by seal line between the bipolar plates and membrane electrode assembly.
The back be equipped with it is a plurality of, the seal line is arranged in the groove between flanging and adjacent back.
The angle of the flanging is less than 90 °.
Compared with prior art, the utility model has the following advantages：
(1) assembly is easy：By bipolar plates corner cut structure, flanging is formed so that bipolar plates can be automatically right by inclined-plane
Together, without using positioning tool so that assembling is more easy and efficient.
(2) protection MEA (membrane electrode assembly)：By the control of corner cut structural thickness, stop surface is designed, is effectively controlled
The decrement of MEA ensures that MEA will not be excessive and damaged because of decrement.
(3) MEA performances are improved：Since decrement is under control, it is ensured that MEA is assembled under best decrement,
Improve the overall performance of fuel cell pile.
(4) raising of pile consistency：Since decrement is uniformly controlled so that the performance of every MEA tends to one
It causes, avoids not using due to the bad caused whole pile of monolithic performance.

Specific implementation mode
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, gives detailed embodiment and specific operating process, but the guarantor of the utility model
Shield range is not limited to following embodiments.
Embodiment
As shown in Figure 1, a kind of bipolar panel assembly of fuel cell pile, including bipolar plates 2, membrane electrode assembly, sealing knot
Structure.
The utility model devises the downward flanging 5 in inclined-plane in the outside of bipolar plates 2, and there are back 12 and membrane electrode assembly in inside
Part 1 contacts, to compress membrane electrode assembly 1.
Membrane electrode assembly 1 is mainly made of the frame 4 of internal CCM8, both sides diffusion layer 7 and outside.
The predominantly upper seal line 6 of sealing structure and lower seal line 3 composition.
The effect of each critical piece in utility model device：
Membrane electrode assembly 1：Electrochemical reaction mainly carries out herein, consumes hydrogen and oxygen, generates electric energy, thermal energy and water.
Bipolar plates 2：Uniform flow field is provided, to ensure the efficient progress of reaction.
Upper seal line 3, lower seal line 6：Reaction gas is sealed, ensures safety.
Frame 4：Completely cut off gas, insulate between positive and negative anodes.
Flanging 5：It is easily installed, support stop surface is provided.
Lower stop surface 9, upper stop surface 10：Maximum compressibility is controlled, protects membrane electrode assembly not mechanically damaged.
Operation principle：
The outside of bipolar plates 2 devises flanging, forms flanging 5,5 height of flanging is than 12 slightly higher, the specific size of height of back
Depending on 1 size of membrane electrode assembly, control 1 decrement of membrane electrode assembly is within the scope of decrement allowable, general decrement
Control is between 10%~30%.During fuel cell pack assembles, due to the effect at oblique angle, every piece of bipolar plates 2 are pushing
Automatic aligning is understood in the process, is installed without using additional positioning tool.Simultaneously because the integral thickness of flanging 5 can be more than
12 region of back, therefore during pushing, flanging 5 can be contacted with frame 4 first, generate lower stop surface 9, upper stop surface 10,
Such design can be with the membrane electrode assembly 1 inside effective protection, and the control simultaneously for pile overall dimensions also can be more accurate
Really efficiently, the decrement of membrane electrode assembly 1 is constant, then the state of reaction zone can also be kept constant, and be conducive to fuel battery performance
Holding consistency extends pile service life.
