Description
Technical field
The present invention relates to field of fuel cell technology, more particularly to a kind of fuel battery double plates leakproofness on-line checking system
System.
Background technology
Methanol fuel cell, directly as raw material, as a proton exchanging film fuel battery, needs to use using methanol
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 are known as bipolar plates.Bipolar plate flow field structure is complicated, and difficulty of processing is big, to material performance requirement
The performance of height, material is relatively low, and fuel cell can be caused to occur, and working performance is unstable, inefficient problem.Bipolar plates conduct
Important component when fuel cell power generation, need between two pieces of bipolar plates to be sealed formed with MEA (membrane electrode) it is close
Seal space.
There are mainly two types of the sealing structures of the bipolar plates of the prior art, first, clamping the sealing of O shapes between two pieces of bipolar plates
Circle, this technique production efficiency in production is relatively low, and product yield also cannot be guaranteed；Second is that being used between two pieces of bipolar plates
Gluing process, one circle of surrounding movement using dispenser in bipolar plates carry out dispensing, viscosity and drying of this technique to glue
Time etc. has higher requirements, and once can only be in the surface coating of one piece of bipolar plates, and production efficiency is relatively low.In addition, bipolar
The detection of leakproofness is mostly being carried out after assembling bipolar plates between plate, in this way if there is bad, it is necessary to be spent a large amount of
Time energy go to repair, production efficiency is not high.Therefore, how to design one kind can quickly injecting glue and can on-line checking it is close
The system of envelope property is exactly the present inventor's problem to be solved come the scheme for improving production efficiency.
Invention content
It being capable of quick injecting glue leakproofness in view of the deficienciess of the prior art, the main purpose of the present invention is to provide one kind
It is good, and it is capable of the system of on-line checking leakproofness.
To achieve the above object, the present invention provides following technical solutions：A kind of on-line checking system of bipolar plates leakproofness
System, including bipolar plates, nitrogen charging device and injecting glue template, the bipolar plates include seal groove, anode interface and cathode interface,
The injecting glue template includes injecting glue conduit, and the form and dimension of the injecting glue conduit is identical as seal groove, the seal groove and
Glue is full of in injecting glue conduit, the anode interface and cathode interface are connected separately with and rush nitrogen device.
Preferably, the injecting glue conduit includes glue import and glue outlet, and the glue import and glue outlet are diagonal
Setting.
Preferably, described two nitrogen charging devices are alternately filled with nitrogen into bipolar plates.
Preferably, each nitrogen charging device is filled with nitrogen into bipolar plates 3 times respectively.
Preferably, the glue import and glue exit are both provided with sector open.
The present invention has the following advantages compared with the prior art, and carries out bipolar plates with injecting glue template to be aligned fastening first,
Then glue is injected into the injecting glue conduit of injecting glue template, then two nitrogen charging devices are started to work, two nitrogen charging devices
It is connect respectively with the anode interface of bipolar plates 1 and cathode interface, two nitrogen charging devices alternately pour nitrogen into bipolar plates respectively
Gas, then detaches bipolar plates with injecting glue template, checks that the glue in bipolar plates seal groove is said if there is bubble
Bright poor sealing, no bubble illustrate that leakproofness is good.Entire detecting system is imitated true using the form of alternately inflated with nitrogen
Real operating mode when using, can accurately measure the leakproofness of bipolar plates very much, easy detection method compared with the existing technology,
Testing result is more valuable.And can when detecting bad can scene do over again, save the time, improve work
Efficiency.

Specific implementation mode
The invention will be further described with attached drawing for knot below.
As shown in Figure 1 to Figure 3, a kind of on-line detecting system of bipolar plates leakproofness, including bipolar plates 1, nitrogen charging device 2
And injecting glue template 3, the bipolar plates 1 include seal groove 4, anode interface 5 and cathode interface 5, the injecting glue template 3 includes note
The form and dimension in glue groove road 7, the injecting glue conduit 7 is identical as seal groove 4, is full of in the seal groove 4 and injecting glue conduit 7
Glue is connected separately at the anode interface 5 and cathode interface 5 and rushes nitrogen device.
Preferably, two nitrogen charging devices 2 are alternately filled with nitrogen into bipolar plates 1.
Preferably, each nitrogen charging device 2 is filled with nitrogen 3 times into bipolar plates 1 respectively.
A kind of operation principle of the on-line detecting system of bipolar plates leakproofness of the present invention is, first by bipolar plates 1 and note
