Publication number CN101174693 discloses a kind of fuel cell membrane electrode and double-polar plate gas leakage checking device, for solving the gas leakage performance that detects all kinds of difform planes or non-planar material, the technological means adopting is the upper and lower removable air pressure storehouse with four guide rails to be designed to removable, according to difform plane or non-planar material, changes different air pressure storehouses.In order to make the surperficial pressurized of measured sample even, in device, be provided with a pressure buffer storehouse with grid structure in addition.Disclosed these technological means of the disclosure file can only detect separately bipolar plates sampling, cannot realize scale a plurality of bipolar plates are detected.
Publication number CN101069316 discloses a kind of fuel cell system and method for inspecting gas leakage of same thereof, the main order ground of the disclosure content is for after having detected fuel cell impermeability, do not allow inspection gas sneak in fuel cell, mix with fuel gas, reduce the performance of fuel cell.This document has adopted multiple technologies means in order to reach this purpose: in the stream to fuel cell system supply response gas, form the enclosure space that does not comprise fuel cell; In checking gas discharge system, be provided with pressure reducing mechanism, for inspection gas is depressured under authorised pressure; In checking gas discharge system, be provided with the recovering mechanism that checks gas for reclaiming.The open of this document do not solve and how the bipolar plate tightness of fuel cell hunted leak fast, and complicated structure, needs a large amount of manual operationss, and efficiency is lower.
Publication number CN202379140U discloses a kind of leak tester of Packaging Bottle, belong to the field to Packaging Bottle airtight test, the technical matters solving is to provide and a kind ofly can detects the Packaging Bottle leak tester whether Packaging Bottle leaks, in order to address this problem, the disclosed scheme of this document is that Packaging Bottle sealing is divided into bottle interior sealed cavity and bottle external seal cavity, then to pressurizeing in bottle, and bottle outer air is extracted out and formed vacuum state, by Vacuum Pressure device for detecting difference, be to determine whether Packaging Bottle has leakage.The mode of this document disclosure detection draught head is carried out the impermeability of testing product, but can not to a plurality of products, hunt leak simultaneously, bipolar plates belongs to planar materials simultaneously, in disclosure, also the impermeability of planar products is not detected and makes any technology enlightenment.
To sum up, present bipolar plates leakage detection apparatus only can be put leakage detection apparatus and single bipolar plates to hunt leak separately together, and automaticity is not high, needs a large amount of manual operationss, loses time, and inefficiency, is unfavorable for the development of fuel cell industrialization.
Utility model content
Utility model object: the utility model object is for the deficiencies in the prior art, and a kind of fuel battery double plates leak detection mould that can disposablely simultaneously detect multi-disc arbitrary flow field bipolar plates or tabula rasa is provided.
Technical scheme: fuel battery double plates leak detection mould described in the utility model, described leak detection mould external form is cube structure, comprises mould upper plate and mould lower plate, after mould upper plate and mould lower plate coordinate compression, inside forms airtight cavity; Fuel battery double plates to be detected is arranged between mould upper plate and mould lower plate, and the airtight cavity between mould upper plate and mould lower plate is divided into independently upper cavity and lower chamber; On the sidewall of described mould lower plate, be provided with air admission hole, on the sidewall of described mould upper plate, be provided with venthole, venthole is connected with airtight leak locator.
During work, gas is entered the lower chamber of leak detection mould by air admission hole, along with the increase of lower chamber air pressure, if double-polar plate gas leakage, air pressure in leak detection mould upper cavity also can increase thereupon, and gas will enter the leak rate that airtight leak locator is measured bipolar plates by leak detection die vent.Bipolar plates to be checked is placed between the upper and lower plates of mould, can, by increase the disposable multi-disc bipolar plates that detects of a plurality of leak detection moulds simultaneously, increases work efficiency like this.
As preferably, the middle part in described mould upper plate is provided with the upper plate support ridge that prevents bipolar plates distortion.Gas is entered the lower chamber of leak detection mould by the mould air admission hole of hunting leak, along with the increase of gaseous tension, bipolar plates has deformation, if bipolar plates deformation is excessive, can make original qualified bipolar plates because deformation causes damage gas leakage, impact leak detection result.Therefore the middle part in mould upper plate arranges upper plate support ridge, prevents bipolar plates distortion.
As preferably, the middle part in described mould lower plate is provided with the lower plate support ridge that prevents bipolar plates distortion.In situation about using in the inversion of leak detection mould, bipolar plates can be to lower chamber deformation originally, and therefore the middle part in mould lower plate is provided with the lower plate support ridge that prevents bipolar plates distortion.
As preferably, the inwall interface of described mould upper plate and mould lower plate is respectively arranged with step surface, and up/down steps face is common forms the groove with bipolar plates edge matching, and the surrounding of bipolar plates to be detected is arranged in described groove.Mould upper plate and mould lower plate are arranged to and the groove of bipolar plates edge matching can make more laminating between bipolar plates and mould, do not leave space.
As preferably, in described groove, be provided with sealing gasket.Sealing gasket is set in groove and can guarantees the impermeability between lower chamber and upper cavity, can in detection, not allow gas pass through from groove, the result that impact detects.
Beneficial effect: (1) the utility model leak detection mould can be placed in fastener in a plurality of stacks, the gas leakage of one-time detection multi-disc bipolar plates; (2) middle part of the utility model in mould upper plate is provided with the upper plate support ridge that prevents bipolar plates distortion, can effectively prevent bipolar plates generation deformation in leak detection process, causes bipolar plates to be damaged; Middle part in mould lower plate arranges lower plate support ridge is also set simultaneously, and mould can be placed arbitrarily unrestricted; (3) the utility model is at the groove of the inwall interface of mould upper plate and mould lower plate being arranged to bipolar plates edge matching, groove can be provided with sealing gasket, can guarantee to hunt leak completely independent between the upper and lower cavity of mould, make the leak detection data of bipolar plates more accurate; (4) the utility model bipolar plates leak detection mould can detect bipolar plates or the tabula rasa of arbitrary flow field, very easy to use.
