Technical field
The invention belongs to fuel cell fields, more particularly, to a kind of graphite bi-polar plate air-tightness detection device.
Background technology
Bipolar plates are performance components important in fuel cell pack, and both sides, which are equipped with, makes the equally distributed runner of reactant, it
It is responsible for fuel and air to be assigned to two electrode surfaces and battery pile radiates, therefore is more demanding to its air-tightness, at present
The material that bipolar plates most generally use is graphite, and graphite bi-polar plate is usually to mix graphitizable resin using carbon dust or graphite powder
It is prepared, it, may existing defects in preparation process so that and graphite, which double-clicks plate matrix, may have airtight sex chromosome mosaicism,
If air-tightness is bad, harmful effect can be generated to the performance of fuel cell.
Chinese patent CN106025402A discloses a kind of on-line detecting system of bipolar plates leakproofness, first by bipolar plates
It carries out being aligned fastening with injecting glue template, then injects glue into the injecting glue conduit of injecting glue template, then two nitrogen charging devices
It starts to work, two nitrogen charging devices are connect with the anode interface of bipolar plates and cathode interface respectively, two nitrogen charging devices point
Nitrogen Jiao Ti not be poured into bipolar plates, then detaches bipolar plates with injecting glue template, checked in bipolar plates seal groove
Glue illustrates that poor sealing, no bubble illustrate that leakproofness is good if there is bubble.It is only used for sealing position
Air-leakage test can not be used for the air-leakage test of graphite cake matrix, and can only carry out qualitative detection to air-tightness, can not
Calculate leakage rate.
