[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Referring to Figure 1 - Figure 3 , an embodiment provided by the present utility model: a test device for the separation efficiency of a fuel cell water separator, including a heating water tank 5. A second water supply pipe 11 is fixedly connected inside the heating water tank 5. One end of the second water supply pipe 11 is fixedly connected to a metering pump 4. The output end of the metering pump 4 is fixedly connected to a first water supply pipe 10. One side of the outer wall of the metering pump 4 is fixedly connected to a separated water collection tank 3. There is a pipe assembly on the outer wall of the separated water collection tank 3 for discharging separated water and gas. The pipe assembly includes a separated water output pipe 7 and an exhaust pipe 12. One ends of the separated water output pipe 7 and the exhaust pipe 12 are both fixedly connected inside the separated water collection tank 3. One end of the first water supply pipe 10 is fixedly connected to a spray tank 1. A liquid level gauge 2 is fixedly connected inside the separated water collection tank 3. A humidifying gas input pipe 6 is fixedly connected inside the spray tank 1. A water separator connection pipe 8 is fixedly connected inside the spray tank 1. A spray gas input pipe 9 is fixedly connected inside the spray tank 1;

[0022] Specifically, when testing the separation efficiency of the fuel cell water separator, first, the humidifying gas is introduced into the spray tank 1 through the humidifying gas input pipe 6. In the spray tank 1, the humidifying gas undergoes heat preservation and humidification treatment through the spray system. The spray system consists of two parts: water supply and gas supply. Among them, the spray gas enters the spray tank 1 through the spray gas input pipe 9 and is sprayed through the atomizing nozzle. The water supply part involves the water in the heating water tank 5 being heated by the heater and then being supplied to the spray tank 1 through the water supply pipe 10 and the water supply pipe 11 under the precise control of the metering pump 4. The supply frequency of the metering pump 4 can be precisely adjusted to achieve precise control of the spray water flow rate. After the humidifying gas is fully mixed with the atomized water in the spray tank 1, a water-gas mixture is formed. Subsequently, the water-gas mixture enters the fuel cell water separator through the water separator connecting pipe 8. In the water separator, the water-gas mixture undergoes a water-gas separation process, and the separated water flows into the separated water collection water tank 3 through the separated water output pipe 7. The combination of the diameter of the separated water collection water tank 3 and the reading of the liquid level gauge 2 can accurately calculate the amount of water separated by the water separator. Through the above precise test process and data collection, the separation efficiency of the fuel cell water separator can be accurately calculated. The calculation of this efficiency is based on the ratio of the amount of water separated to the total amount of water in the water-gas mixture entering the water separator. The design of this test device aims to simulate the water-gas separation conditions in the actual operation of the fuel cell, ensuring the accuracy and reliability of the test results, thereby providing a scientific basis for the performance evaluation and optimization of the fuel cell water separator.

[0023] Working principle: When using the test device for the separation efficiency of the fuel cell water separator, first, the humidifying gas is introduced into the spray tank 1 through the humidifying gas input pipe 6, and then heat preservation and humidification are carried out through the spray of the spray system. The spray system is supplied by water supply and gas supply. The spray gas enters the spray tank 1 through the spray gas input pipe 9 and is then sprayed through the atomizing nozzle. The water comes from the heating water tank 5 heated by the heater and is supplied to the spray tank 1 by the metering pump 4 through the water supply pipe 10 and the water supply pipe 11. By controlling the supply frequency of the metering pump 4, the water flow rate of the spray can be controlled. The spray gas is provided by the gas supply system. The water-gas mixture after spraying in the spray tank 1 enters the fuel cell water separator through the water separator connecting pipe 8. The water separator separates the water and gas, and the separated water will flow into the separated water collection water tank 3 through the separated water output pipe 7. Through the combination of the diameter of the separated water collection water tank 3 and the liquid level detected by the liquid level gauge 2, the amount of separated water by the water separator can be calculated, and then the separation efficiency of the water separator can be accurately calculated.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
