the second container 2 is arranged within the third container 3.
Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In a first aspect, referring to fig. 1 to 3, an embodiment of the present application provides an electrolytic hydrogen production apparatus, including:
a first container 1, wherein the first container 1 is used for producing hydrogen by electrolysis;
the second container 2 is used for containing a first liquid for hydrogen production through electrolysis, and the second container 2 is communicated with the first container 1;
a third container 3 for heating the second container 2 by means of water bath heating;

And a second part, temperature control:
according to the working requirement of the hydrogen production electrolytic cell, inputting a corresponding target temperature value in an 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 further changed, and the temperature of the first liquid in the second container 2 is further 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;
the auxiliary heating rod is inserted into the first container 1, namely the end plate of the electrolytic cell, and is used for controlling the temperature in combination with the thermocouple and the temperature control system, and the electric heater 30 is used for controlling the temperature mainly and secondarily so as to achieve accurate temperature control;
the electric heater 30 may be an electric heating rod, among others.
And a third part, power control:
according to the working requirement of the hydrogen production electrolytic cell, a corresponding current and voltage value is input into the upper computer, the direct current power supply module can supply power to the first container 1, namely the hydrogen production electrolytic cell, according to the input value, specifically, the cathode and the anode in the first container 1, namely the cathode and the anode of the electrolytic cell, are controlled, and meanwhile, the real-time voltage and current of the electrolytic cell are fed back to the upper computer to form a current and voltage real-time curve.
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.
Further, the electrolytic hydrogen production apparatus further includes:
a cell cathode heating sheet 10 provided on the cathode of the first container 1;
an electrolytic cell anode heating sheet 11 provided on the anode of the first container 1;
the temperature controller 4 is also used for controlling the cathode heating plate 10 and the anode heating plate 11 of the electrolytic cell to respectively regulate the temperature of the cathode and the anode according to the temperature of the cathode and the anode of the first container 1.
Further, the electrolytic hydrogen production apparatus further includes:

Further, the electrolytic hydrogen production apparatus further includes:
an auxiliary heater 14 disposed inside the first container 1;
the temperature controller 4 is further configured to control the electric heater 30 to heat the water in the third container 3 according to a first heating cycle based on the water temperature in the third container 3 and the first target temperature;
the temperature controller 4 is further configured to control the auxiliary heater 14 to heat the inside of the first container 1 according to a second heating cycle based on the temperature inside the first container 1 and a second target temperature.
Here, the operation flow of the electric heater 30 and the auxiliary heater 14 will be specifically described:
when the electrolytic hydrogen production starts, the electric heater 30 is controlled to work firstly, preheating operation is carried out, so that the water in the third container 3 reaches the corresponding preset temperature, and then the second container 2 is heated in a water bath heating mode, so that the temperature of the first liquid in the second container 2 reaches the corresponding preset temperature;
then the electrolytic hydrogen production work is carried out, and the temperature of the first liquid in the second container 2 and the temperature in the first container 1 are monitored at the same time,
since the first liquid may lose heat during the process of transferring from the second container 2 to the first container 1, an insulating layer is required to be disposed on the pipeline for transferring the first liquid from the second container 2 to the first container 1, and the electric heater 30 and the auxiliary heater 14 are also used for combined temperature control.
When the temperature is controlled jointly, when the temperature difference between the temperature of the first liquid in the second container 2 and the corresponding preset temperature exceeds the corresponding temperature difference threshold, the electric heater 30 is controlled to heat the water in the third container 3 according to the first heating cycle, so that the temperature difference between the temperature of the first liquid in the second container 2 and the corresponding preset temperature is smaller than the corresponding temperature difference threshold,
when the temperature difference between the temperature of the first liquid in the first container 1 and the corresponding preset temperature exceeds the corresponding temperature difference threshold, controlling the auxiliary heater 14 to heat the interior of the first container 1 according to a second heating period, wherein the temperature difference between the temperature of the first liquid in the first container 1 and the corresponding preset temperature is smaller than the corresponding temperature difference threshold;
it should be noted that, the periodic heating mode is adopted to controllably and slowly raise the temperature to a certain extent, so as to achieve the effect of joint temperature control and avoid heat loss caused by hardware structure problems.
Wherein, when the combined temperature control is implemented, the preset temperature can be 60 ℃, and the temperature difference threshold can be 1 ℃;
the first heating period and the second heating period may be 1 second or 2 seconds or other values, and each of the first heating period and the second heating period may be separated by a preset separation time, for example, 1 second or 2 seconds;
that is, when the temperature difference between the temperature of the first liquid in the first container 1 and the corresponding preset temperature exceeds the corresponding temperature difference threshold, the auxiliary heater 14 is heated for 1 second, then stopped for 1 second, then heated for 1 second, and then stopped for 1 second, until the temperature difference between the temperature of the first liquid in the first container 1 and the corresponding preset temperature is smaller than the corresponding temperature difference threshold, the operation mode of the electric heater 30 is similar.
Further, the electrolytic hydrogen production apparatus further includes:
