There is energy conversion efficiency high, the features such as environment-friendly, it is considered to be clean, the efficient hair of 21 century first-selection
Power technology.
Membrane electrode is the place that electrochemical reaction occurs, and the chemical energy in this fuel is converted into electric energy.
The demand that a battery for membrane electrode is comprised only when can not meet outside high-power electricity consumption, it is therefore desirable to by more piece
Cells in series gets up to constitute pile.Pile is general by tens of sections to section single battery groups up to a hundred into these single electricity
Pond is stacked by way of straight folded or tiling, along with collector plate, insulation board and end plate, is utilized
Screw rod or card article are fastened, and constitute fuel cell pile.
Fuel cell pile assembling quality has extremely important influence, pile assembling process meeting on the performance of battery
Influence pile internal resistance and because the fuel that stress is caused distributes uneven.When tens of sections to the single electricity of sections up to a hundred
Pond is stacked up when constituting pile, it is necessary to cut out The fuel stream road junction and inside on the membrane electrode in each single pond
Trip bolt/positioning port.The fuel stream road junction and internal screw mouthful are high relative to diffusion layer position requirement on machining accuracy,
This for whole pile performance and be sealed with large effect.It is mainly shown as：1. each monocell is in group
If without good positioning during dress, there is assembling dislocation, this can cause fuel cell pile inside stress not
, influence sealing even damages membrane electrode assembly and bipolar plates.2. positioning and machining tolerance add up to cause
Distortion, this distortion are produced when being assembled to battery pack can make that relative displacement occurs between MEA components and bipolar plates,
Public runner size and shape is influenceed, fluid distribution is uneven between causing single pond, influences Performance data.It is existing to set
It is standby to be insufficient for the demand that fuel cell cuts to membrane electrode.
The content of the invention
The present invention is in view of the shortcomings of the prior art, purpose is to provide a kind of fuel cell membrane electrode cross cutting
Device, is used to ensure that sprue hole and internal trip bolt/positioning port are relative to diffusion layer position essence on membrane electrode
Really, and improve production efficiency.The present invention is realized using following technical scheme:
A kind of fuel cell membrane electrode die-cutting apparatus, including die cut systems, the vacuum generation being fixed in frame
System, light source alignment system, pressure system；
Described die cut systems include constituting cutting die and lower bolster by more than 1 blade being fixed on support,
Lower bolster is placed on a fixed mount, and cutting die is located at lower bolster top, the blade and lower bolster phase of cutting die cutter
To setting, lower bolster is a flat board, and flat board upper surface offers a section with film electroplax shape and size to be cut
The groove of identical first, a section is offered with film electroplax diffusion layer to be cut in the first bottom portion of groove central region
The groove of shape and size identical second, opened up in the first bottom portion of groove of the second groove region surrounding
There is through hole, membrane electrode to be cut can be fixed using groove；Through hole is connected with vacuum generating system；
Light source alignment system and cutting die Joint；Pressure system is connected with cutting die.
The vacuum generating system is a vavuum pump or aspiration pump；Vacuum generating system is mainly used in fixing film electricity
Pole, prevents membrane electrode from being moved in die cutting process.
Described light source alignment system is that can launch more than two light sources of intersecting " one " word light, is used to
Membrane electrode to be cut is positioned；The light source alignment system can be detected on membrane electrode where membrane electrode part to be cut
Position, and the adjustment to membrane electrode position is realized using the servomotor being connected with lower bolster fixed mount.
Described pressure system provides power for cutting die, and it can be a motor or air pump or hydraulic press, make cutting die
Move up and down, force process includes two steps of precompressed and supercharging.
The application method of the fuel cell membrane electrode die-cutting apparatus, comprises the following steps：
(1) cutting die mechanism is installed, " one " word light source position is calibrated；
(2) membrane electrode is placed in the first groove of lower bolster, adjustment membrane electrode position starts vacuum and inhales
Attached fixed membrane electrode；
(3) lower bolster that will fix membrane electrode moves to cutting die lower section, starts pressure system completion cross cutting dynamic
Make；
(4) membrane electrode being punched is taken out.
The present invention is fixed, is segmented force mechanism to film using limit method, light source alignment system, vacuum suction
Electrode carries out one-step punching, and the equipment may insure sprue hole and internal trip bolt/positioning port on membrane electrode
It is accurate relative to diffusion layer position, and improve production efficiency is limited, improve Performance data.
