Description
Technical field
The utility model is related to right technical field of lithium batteries, particularly to a kind of dispensing sealing dress of right material cell bipolar plate
Put.
Background technology
Methanol fuel cell uses methyl alcohol directly as raw material, as a proton exchanging film fuel battery, needs to use
A kind of conductive separator plate, with support, afflux, separates oxidant and reducing agent, and guides Oxidizing and Reducing Agents electrode in battery
Surface flow, this conductive separator plate is referred to as bipolar plates.Bipolar plate flow field structure is complicated, and difficulty of processing is big, to material performance requirement
Height, the performance of material is relatively low, and fuel cell can be led to occur, and service behaviour is unstable, inefficient problem.Bipolar plates conduct
Important component part during fuel cell power generation, need between two pieces of bipolar plates to carry out sealing come with mea (membrane electrode) formed close
Envelope space.
The sealing structure of the bipolar plates of prior art mainly has two kinds, and one is to clamp the sealing of o shape between two pieces of bipolar plates
Circle, this technique production efficiency when producing is relatively low, and product yield also cannot be guaranteed；Two is to adopt between two pieces of bipolar plates
Gluing process, carries out dispensing using point gum machine in surrounding motion one circle of bipolar plates, this technique is to the viscosity of glue and drying
Time etc. all has higher requirements, and once can only be relatively low in the surface coating of one piece of bipolar plates, production efficiency.
Utility model content
In view of the shortcomings of the prior art, main purpose of the present utility model is to provide a kind of good sealing effect and life
Produce the dispensing sealing device of the fuel battery double plates of efficiency high.
For achieving the above object, the utility model provides a kind of following technical scheme: dispensing of fuel battery double plates
Sealing device, including body, described body is provided with glue conduit, described glue conduit includes glue import and glue goes out
Mouthful, described body is additionally provided with and supports, with bipolar plates, the cushion block setting, the thickness of described cushion block is identical with the depth of glue conduit.
Preferably, described glue conduit be shaped as rectangle, described glue import and glue export and arrange for diagonal.
Preferably, described glue import and glue exit are provided with sector open.
Preferably, the sealing groove shape on the width of described glue conduit and bipolar plates and width all same.
The utility model has the advantage that with respect to prior art, first bipolar plates lid is located on body, makes glue
Conduit is corresponding with the seal groove in bipolar plates, can be using attachment device pressing.Cushion block is supported with bipolar plates and sets, such point gum machine
Nozzle or directly convey glue from glue entrance is to glue conduit using glue rifle, glue will not be revealed.Glue is filled
Flow out from glue exit after glue conduit, represent in glue conduit and be filled with glue.So body and bipolar plates are carried out point
From then operating to next block bipolar plates, the time is short, efficiency high, one piece of block assembled through bipolar plates for dispensing glue
Pressing, good sealing effect, high working efficiency.Wherein the material selection of body and glue are difficult the material bonding, or in body
On be surface-treated, such glue is just easier to separate with body.
Brief description
Fig. 1 is a kind of dispensing sealing device and structure during bipolar plates cooperation of fuel battery double plates of the present utility model
Schematic diagram；
Fig. 2 is a kind of structural representation of the dispensing sealing device of fuel battery double plates of the present utility model.
In figure: 1, body；2nd, glue conduit；3rd, glue import；4th, glue outlet；5th, cushion block；6th, bipolar plates.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of dispensing sealing device of fuel battery double plates, including body 1, described body 1 is arranged
There is glue conduit 2, described glue conduit 2 includes glue import 3 and glue outlet 4, and described body 1 is additionally provided with and bipolar plates
6 support the cushion block 5 setting, and the thickness of described cushion block 5 is identical with the depth of glue conduit 2.
The operation principle of the dispensing sealing device of fuel battery double plates of the present utility model is to cover bipolar plates 6 first
It is located on body 1, make glue conduit 2 corresponding with the seal groove in bipolar plates 6, can be using attachment device pressing.Cushion block 5 with
Bipolar plates 6 support set, the nozzle of such point gum machine or directly use glue rifle at glue import 3 in glue conduit 2 conveying glue
Liquid, glue will not be revealed.Glue flows out after filling glue conduit 2 at glue outlet 4, represents in glue conduit 2 and is filled with glue
Liquid.So body 1 is separated with bipolar plates 6, then next block bipolar plates 6 is operated, the time is short, efficiency high, will
One piece of block carries out assembling pressing, good sealing effect, high working efficiency through bipolar plates 6 for dispensing glue.The material selection of wherein body 1
It is difficult the material of bonding with glue, or is surface-treated on body 1, such glue is just easier to separate with body 1.
Preferably, glue conduit 2 be shaped as rectangle, glue import 3 and glue outlet 4 are diagonal setting.Because double
The shape of pole plate 6 is mostly rectangle, thus glue conduit 2 be preferably shaped to rectangle.Glue import 3 and glue outlet 4
Benefit for diagonal setting is that glue just can flow out it is ensured that filling in glue conduit 2 after being full of glue conduit 2 at glue outlet 4
Full glue.
Further, it is provided with sector open at glue import 3 and glue outlet 4.Point gum machine so can be facilitated
The nozzle of nozzle or glue rifle is fully identical with glue import 3, and easily clears up when glue flows out.
In addition, sealing groove shape and width all same in the width of glue conduit 2 and bipolar plates 6 are it is ensured that glue conduit 2
Fit like a glove with seal groove, ensure that sealing during injecting glue simultaneously.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonging under the utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from the utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
