The invention discloses a hydrogen fuel cell testing device and method. The hydrogen fuel cell testing device comprises a hydrogen fuel cell placed in a testing table. The top end of the testing table is fixedly connected with a first water storage tank, a first gas storage tank, a second gas storage tank and a second water storage tank. The top ends of the first water storage tank, the first gas storage tank, the second gas storage tank and the second water storage tank are all connected with flexible connecting pipes used for being communicated with the interior of the hydrogen fuel cell. The tail ends of the flexible connecting pipes are fixedly connected with rigid connecting pipes, and the circumferential surfaces of the rigid connecting pipes are fixedly sleeved with first connecting plates. Clamping blocks are symmetrically connected to the two sides, in the axial extending direction of the rigid connecting pipes, of the first connecting plates, and a first wide-mouth hose, a wide-mouth rigid pipe and a fixing ring are sequentially arranged between the two clamping blocks. The flexible connecting pipes are in butt joint with the rigid through pipes, so that the second wide-mouth hose can be extruded in an interlayer between the first wide-mouth hose and the wide-mouth rigid pipe, the connection airtightness of the flexible connecting pipes and the rigid through pipes is effectively improved, and leakage of gas and ionized water is avoided.
Description
technical field [0001] The invention belongs to the technical field of battery testing, and in particular relates to a hydrogen fuel cell testing device and method. Background technique [0002] Before the hydrogen fuel cell is used, it needs to be tested and processed. During the test, the internal humidified gas and ionized water need to be tested. During the test, the water storage tank, the gas storage tank and the hydrogen fuel cell are required to be connected The airtightness is good, otherwise the leakage of gas and ionized water will directly lead to the deviation of the test data. In the prior art, a patent document with the application number 202010901755.4 titled a hydrogen fuel cell test bench humidification gas and battery stack water balance detection device is disclosed. The relevant technical problems are also recorded in this document. In order to solve the above technical problems , by inserting the connecting pipe into the inside of the through pipe, aft...
