And a second part, temperature control:

according to the test condition of the electrolytic cell, inputting a corresponding target temperature value in the upper computer, and changing the control current of the electric heater 30 in the third container 3 by the electric control system according to the input target temperature value, so that the heating power of the electric heater 30 is changed, the temperature of water in the third container 3 is changed, and the temperature of the first liquid in the second container 2 is changed in a water bath heating mode;

meanwhile, the corresponding thermocouple feeds back the temperature monitored in real time to the temperature control system, and the starting and stopping of the electric heater 30 are controlled according to the set target temperature value, so that the temperature of the water in the third container 3 deviates from the set value, and the overhigh temperature caused by the continuous heating of the electric heater 30 is avoided.

When necessary, due to heat dissipation of the pipeline, the heat can reach the first container 1, namely after the hydrogen production electrolytic cell, the actual temperature is lower than the temperature required by the test, and an auxiliary heating system is needed;

And the fourth part is hydrogen production flow monitoring:

after hydrogen is produced by electrolysis, hydrogen is produced in the hydrogen discharge pipeline, the working efficiency of the electrolytic cell can be judged according to the flow of the produced hydrogen in unit current time, and the working power of the cathode and the anode in the first container 1 is adjusted;

when necessary, in order to ensure the monitoring precision, a hydrogen flow meter used for monitoring the flow can be replaced by a hydrogen flow sensor.
