In terms of existing technologies, advantageous effect is a kind of MEA detections fixture provided by the utility model：The prior art
When MEA is detected and assembled, mostly monolithic detects, and fixture can only simulate monolithic MEA assembled states.A small number of technologies can be to MEA simultaneously
Hunt leak, when carrying out multi-disc MEA detections, existing fixture need first to install on the MEA bipolar plates matched and existing fixture
Without positioning device, i.e. prior art bipolar plates are not pre-installed on detection fixture, when being carried out at the same time multi-disc MEA leak detections,
It needs first to assemble bipolar plates and reassembles MEA, operation is comparatively laborious, and detection is also required to manually separate bipolar plate piece right when finishing
After take out MEA.
MEA detections fixture provided by the utility model detects simultaneously suitable for multi-disc MEA, is installed in advance on detection fixture
There are bipolar plates, and fixture has positioning device, the placement and positioning of MEA is very convenient.When multi-disc is detected, the utility model
MEA detection fixture can the true assembled state of analog fuel battery；When detection finishes, the MEA detection folders of the utility model
The bipolar plates of tool can automatically open, and the taking-up of MEA is very convenient.It is easy to detect quick, the detection need commercially produced can be met
It asks.
Based on the structure, this kind of MEA detects fixture, during implementation, is equipped with location guide on pedestal, bipolar plates are bushed in fixed
On the guide rod of position, location guide runs through pressing plate, and extensible member is equipped between bipolar plates and bipolar plates, can under platen pressure effect
It is closed with realizing to compress.When pressing plate pressure release, bipolar plates separate automatically under the action of extensible member, facilitate putting for MEA to be measured
Enter and take out.
During detection, multi-disc MEA is respectively put among bipolar plates, control driving device presses to pressing plate.
Preferably, pressure sensor is equipped at pressing plate.
Preferably, after pressure sensor reaches assembling pressure 100PSI, gas is passed through from pressing plate hydrogen inlet, is then shut off
Hydrogen gas outlet, and open oxygen intake and outlet.
It is understood that both can detect whether oxygen entrance has gas leakage with bubbling method by being inserted into water,
Also gas flowmeter can be connected in oxygen entrance and quantitative detection is carried out to leakage rate.
Criterion is：When hydrogen inlet is passed through gas and closes hydrogen outlet, oxygen entrance is accessed in water, if
Go out in oxygen or entrance detects that bubble generates, then illustrate that hydrogen-oxygen mutually leaks, then illustrate that MEA is damaged or there are problems that encapsulation, i.e. MEA
Gas leakage cannot be used for production pile.
It follows that bipolar plates need not be installed by being detected when fixture hunts leak to MEA by the MEA, leak detection is greatly simplified
Cumbersome property.
