In the past, the sealing of the stack was tested by applying foam water on the surface and ventilating the stack, but this method is not intuitive.

[0003] The prior art patent document with publication number CN209589368U provides a liquid flow battery stack air tightness detection device, which can shorten the detection time by pouring water from the overflow tank into the water tank to immerse the stack. In addition, visualization windows are provided around the water tank and a light source is provided at the bottom, so the leakage position of the stack can be directly observed. Therefore, the air tightness detection device is simple to operate, highly safe, directly observes air tightness, has a high detection rate, and small leaks are also very easy to observe.

[0004] The above-mentioned prior art, although the air tightness of the liquid flow battery is directly observed by placing it in a water tank, water droplets will remain on the surface of the liquid flow battery after the air tightness test.
