Example 1
The present embodiment discloses a fuel cell hydrogen test system, as shown in fig. 1, the fuel cell hydrogen test system includes: a heat exchanger 9, a stack simulator 21, a water supply module, a hydrogen supply module, and a hydrogen circulation pump 25. The heat exchanger 9 has a first hydrogen flow channel and a first water flow channel, and the pile simulator 21 is used for simulating a pile under a working condition to be tested. The water supply module comprises a heating water tank 42, a booster pump 29 and a radiator 41, wherein the booster pump 29 is connected between an outlet of the heating water tank 42 and an inlet of the first water flow passage through a pipeline so as to suck out and pressurize the heated water 44 in the heating water tank 42 and send the water to the inlet of the first water flow passage, and the outlet of the first water flow passage is connected with the inlet of the heating water tank 42 through a pipeline. The hydrogen supply module is used for supplying hydrogen, the hydrogen supply module is connected with an inlet of the first hydrogen flow channel through a pipeline, an outlet of the first hydrogen flow channel is connected with an inlet of the pile simulator 21 through a pipeline, and a proportional valve 12 for reducing the pressure of the hydrogen is arranged between the outlet of the first hydrogen flow channel and the inlet of the pile simulator 21. The hydrogen circulation pump 25 is connected between the outlet of the stack simulator 21 and the outlet of the first hydrogen flow channel, and is configured to suck out, pressurize and return the hydrogen passing through the stack simulator 21 to the outlet of the first hydrogen flow channel. At least one temperature sensor and at least one pressure sensor are provided on the path of the hydrogen gas flow and the flow path of the water 44, and a hydrogen gas flow meter 6 is provided between the hydrogen gas supply module and the inlet of the first hydrogen gas flow channel. In the present embodiment, the cell stack simulator 21 is a buffer tank.
In the present embodiment, the heat exchanger 9 can exchange heat between the hydrogen gas passing through the first hydrogen flow channel and the water 44 passing through the first water flow channel, so that the temperatures of the media in the first hydrogen flow channel and the first water flow channel are neutralized, the temperature adjustment of the hydrogen gas is completed, and the heat exchange is realized. The proportional valve 12 mainly reduces the pressure of the hydrogen gas at the front end, and the reduced pressure hydrogen gas is supplied to the inlet of the stack simulator 21, thereby performing the function of regulating the pressure of the hydrogen gas. The hydrogen circulating pump 25 can suck out and pressurize the hydrogen passing through the electric pile simulator 21, and then the hydrogen flows back to the outlet of the first hydrogen runner, so that the hydrogen passing through the heat exchange can be recycled, and the hydrogen utilization rate can be improved.
Among these, the reason why the proportional valve 12 needs to be provided at the rear end of the heat exchanger 9 is as follows: the pressure control effect of the proportional valve 12 is related to the size of the cavity at the rear end thereof (if the cavity is larger, the pressure control effect of the proportional valve 12 is not good), and if the heat exchanger 9 is arranged at the rear end of the proportional valve 12, the pressure control effect of the proportional valve 12 is affected because the cavity inside the heat exchanger 9 is larger.

Wherein the same reference numerals as in embodiment 1 in the present embodiment denote the same elements.
As shown in fig. 3, the fuel cell hydrogen test system further includes a humidifier 16, and the humidifier 16 is located between the proportional valve 12 and the stack simulator 21, and between the heat exchanger 9 and the heating water tank 42.

The hydrogen circulating pump 25 is connected between the outlet of the stack simulator 21 and the outlet of the second hydrogen flow channel, and is configured to suck out, pressurize and return the hydrogen passing through the stack simulator 21 to the outlet of the second hydrogen flow channel.
In the present embodiment, the humidifier 16 is provided to enable the fuel cell hydrogen testing system to simulate the humidification function of the fuel cell hydrogen subsystem, thereby further improving the efficiency and reliability of the functional analysis of the fuel cell hydrogen subsystem. The reason why the proportional valve 12 needs to be provided at the front end of the humidifier 16 is as follows: the pressure resistance of the humidifier 16 is low, and therefore the humidifier 16 needs to be provided at the end where the pressure is low, and therefore, needs to be provided at the rear end of the proportional valve 12.

Wherein, the pressure, temperature and humidity changes of the hydrogen before and after humidification can be analyzed conveniently by comparing the temperature, pressure and humidity of the inlet and the outlet of the second hydrogen flow channel. Accordingly, by comparing the temperature and pressure of the inlet and outlet of the second water flow passage, it is possible to more conveniently analyze the temperature and pressure change of the water 44 after passing through the second water flow passage.
It should be noted that the water flow meter 39 and the sensors in the present embodiment are also connected to the data recorder 28 described in embodiment 1.
