[0027] Specifically, the air inlet 11, the first air outlet 12 and the second air outlet 13 of each group of test gas ports are interconnected, while adjacent test gas ports are isolated from each other, and each air inlet 11 is connected with an air inlet connector 30. Adjacent air inlet connectors 30 are connected to each other through a communication pipe. The outermost air inlet connector 30 is connected to the external gas source through a gas supply pipe. The air inlet connector 30 can be a tee joint, for example. It can be understood that the last air inlet connector 30 away from the external gas source only needs to be connected to the adjacent air inlet connector 30 on one side, so a two-way joint is used to facilitate the interconnection of each air inlet 11.

[0028] The plug-in 20 is provided with a connecting lug 23. The connecting lug 23 is provided with a fastener 24 screwed to the test base 10. The fastener 24 can be a screw, for example.

At this time, the test gas is introduced into the electrolysis module 40 through the first and second quick connectors 21 and 22. After installation, the airtightness testing device is connected to each electrolysis module 40 to be tested and is immersed in a water tank. The test gas at a predetermined pressure is supplied from the gas inlet 11 by an external gas source and is maintained for a certain period of time. Whether bubbles are generated is observed, so that whether the airtightness of the electrolysis module 40 meets the requirements is judged. The position where bubbles are generated can be used to determine which electrolysis module 40 does not meet the requirements. Thus, batch airtightness testing of the electrolysis module 40 is realized at one time, and the testing efficiency is effectively improved.
