[0002] Hydrogen production and refueling by electrolysis are common energy output devices in energy storage. With the commercialization of fuel cell stacks, the demand for hydrogen refueling has also increased accordingly. Mobile and compact hydrogen production and refueling devices have emerged on the market to meet users' frequent refueling needs.

[0003] However, existing hydrogen storage bottles are usually placed in the gas cylinder warehouse of a small hydrogen production and filling device. The filling process of the hydrogen storage bottles is completed in the gas cylinder warehouse. They are used for a long time and frequently. Since the filling process is completed by boosting the pressure through the pipeline, if there is a leak at the pipeline joint, the continuously leaked hydrogen will accumulate in the chassis. When the power supply is short-circuited or an external fire source occurs, and the ignition threshold is met, there may be a risk of explosion. Utility Model Content

[0035] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0036] like Figure 1-Figure 5 As shown, in the first embodiment of the hydrogen production and charging device of the present invention, the hydrogen production and charging device 10 at least includes a box 100, a base 200 and a partition 290;

[0037] The box body 100 is configured as a rectangular parallelepiped structure with one end open, or as a U-shaped structure, with detachable end plates provided at the left and right end openings to cover the left and right end openings of the U-shaped structure;

[0038] A plurality of through holes (120, 140) are provided on adjacent end surfaces of the box body 100, which are used to cover the base 200;

[0039] The base 200 is a rectangular parallelepiped structure, and a plurality of through slots (110, 130) are provided on its end surface for supporting the box body 100 and the partition 290;

[0040] The partition 290 has a rectangular structure;

[0041] Specifically, the base 200 is provided with a plurality of through slots (110, 130) on its end surface for introducing airflow;

[0042] The box body 100 is detachably mounted on the base 200 and fits in contact with the outer extension of the base 200, wherein a plurality of through holes (120, 140) for exhausting gas are provided on adjacent end surfaces of the box body 100;

[0043] Furthermore, the partition 290 is axially arranged on the base 200, with its bottom end surface being attached to the base 200, and the other end surfaces (such as the upper, left, and right) respectively abutting against the inner end surface of the box body 100, so as to separate the box body 100 into a relatively independent first cavity 100a and a second cavity 100b.

[0044] A first support frame 201 and a second support frame 202 are respectively provided at the front and rear ends of the base 200. The support frames are hollow rectangular parallelepiped structures.

[0045] A first fan 121 is provided in the first cavity 100a, wherein the first fan 121 is fixed to the lower side of the first support frame 201, and the first fan 121 is fitted with a through hole 120 on the box body 100;

[0046] When the first fan 121 is working, a flow of air S10 (eg, Figure 3 As shown), the flowing air flow S10 discharges the hydrogen in the first cavity 100a to the outside of the chassis 200;

[0047] An axially arranged fixing plate 240 is installed on one side of the partition 290 (located inside the second cavity 100b), and the second fan 141 is installed on the outer end surface of the fixing plate 240 and is arranged in contact with another through hole 140 on the box body 100;

[0048] When the second fan 141 is working, an air flow S20 (eg, Figure 2 As shown), the flowing air flow S20 discharges the hydrogen in the second cavity 100b to the outside of the chassis 200.

[0049] Using this technical solution, the box body 100 is divided into an independent first cavity 100a and a second cavity 100b by a partition 290, and the working fans (121 / 141) form flowing airflows (S10 / S20) in the first cavity 100a and the second cavity 100b respectively, so as to draw the hydrogen in the cavity to the outside of the chassis in real time. This can effectively solve the problem of air leakage at the pipe joints. The continuously leaked hydrogen accumulates in the chassis. When the power supply is short-circuited or an external fire source occurs and the ignition threshold is met, there may be a risk of explosion.

[0050] In some embodiments, as Figure 1 As shown, in order to ensure the reliability of airflow, the through grooves can be set as a first through groove (corresponding to 110) and a second through groove (corresponding to 130), which are radially arranged on the base 200, and the first through groove (corresponding to 110) and the second through groove (corresponding to 130) are staggered.

[0051] The first through slot (corresponding to 110 ) and the second through slot (corresponding to 130 ) are adjacently arranged on the base 200 , and the partition 290 separates the first cavity 100 a and the second cavity 100 b , and the external airflow is divided into two paths in the box body 100 .

[0052] In some embodiments, as Figure 1 As shown, in order to ensure the reliability of airflow discharge, the through holes can be set as a first through hole (corresponding to 120) and a second through hole (corresponding to 140), wherein the first through hole (corresponding to 120) and the second through hole (140) are not set on the same end face or opposite end faces.

[0053] Specifically, the first through hole (corresponding to 120) is provided on one end surface of the box body 100 and is fitted with the first fan 121 fixed on the first support frame 201;

[0054] The second through hole (corresponding to 140 ) is provided on an adjacent end face where the first through hole (corresponding to 120 ) is provided, and is arranged in close contact with the second fan 141 provided on the fixing plate 240 .

[0055] In some embodiments, as Figure 3 As shown, in order to maintain the reliability of hydrogen production, a pure water tank 230 and an electrolysis module 250 can be set in the first cavity 100a.

[0056] The pure water tank 230 is used to store water to be electrolyzed, and its TDS value is approximately between 1-10;

[0057] The electrolysis module 250 is used to electrolyze the pure water introduced into the pure water tank 230 to produce hydrogen and oxygen;

[0058] Specifically, the electrolysis module 250 is fixed on the base 200.

[0059] A built-in filter element is provided in the pure water tank 230 for filtering impurities in the water body returning after electrolysis. The pure water tank 230 is provided at the upper end of the electrolysis module 250, and the output port of the pure water tank 230 is connected to the water inlet of the electrolysis module 250 through a pipeline to provide water for its electrolysis.

[0060] In some embodiments, as Figure 3 As shown, in order to ensure the reliability of the water flow into the electrolysis module 250, a water pump 260 and a filter assembly 270 can be set in the box 100.

[0061] Among them, the water pump 260 is used to increase the water flow rate;

[0062] The filter assembly 270 is used to filter impurities in the water entering the electrolysis module 250;

[0063] Specifically, one end of the water pump 260 is connected to an output end of the pure water tank 230 through a pipeline.

[0064] The other end of the water pump 260 is connected to one end of the filter assembly 270 through a pipeline.

[0065] The other end of the filter assembly 270 is connected to the water inlet end of the electrolysis module 250 through a pipeline.

[0066] That is, the water output from the pure water tank 230 is pressurized by the water pump 260, input into the filter assembly 270 for filtration treatment, and then input into the electrolysis module 250 for electrolysis to precipitate hydrogen and oxygen, wherein the oxygen and the electrolyzed water are circulated to the pure water tank 230 through the return pipeline.

[0067] In some embodiments, as Figure 4 As shown, in order to improve the quality of the precipitated hydrogen, a gas-liquid separator 220 and at least one drying component 210 may be provided in the second cavity 100b.

[0068] Among them, the gas-liquid separator 220 is used to process hydrogen containing a small amount of condensate to achieve condensate recovery;

[0069] The drying component 210 is used to absorb water vapor in the hydrogen;

[0070] The second cavity 100b is provided with a positioning plate 212, one end of which is in contact with the side of the partition 290 and is vertically arranged with the partition 290.

[0071] The gas-liquid separator 220 and the drying assembly 210 are respectively fixed on the two end surfaces of the positioning plate 212.

[0072] Specifically, one end of the gas-liquid separator 220 is connected to the hydrogen output end of the electrolysis module 250 through a pipeline, and performs gas-liquid separation on the input hydrogen;

[0073] One end of the drying component 210 is connected to the other end of the gas-liquid separator 220 through a pipeline, and the separated hydrogen is sent to the drying component 210 for secondary adsorption / drying treatment to improve the quality of the hydrogen.

[0074] In some embodiments, as Figure 5 As shown, in order to ensure the reliability of the inflation process, a first electromagnetic valve 281 can be provided in the second cavity 100b, which has a switch function;

[0075] Among them, one end of the first solenoid valve 281 is connected to the other end of the drying component 210 through a pipeline, and the other end of the first solenoid valve 281 is connected to the charging port 310 through a pipeline. When the first solenoid valve 281 is controlled to be turned on, hydrogen with a certain pressure (such as 1MPa-3MPa) in the pipeline is output through the first solenoid valve 281 to control the hydrogen charging state.

[0076] What is needed is that the hydrogen pressure boosting process is to continuously electrolyze and output hydrogen through the electrolysis module 250, so that the pressure of hydrogen is correspondingly increased at each node to meet the inflation demand.

[0077] In some embodiments, as Figure 5 As shown, in order to increase the pressure of the separated water output by the gas-liquid separator 220, a second solenoid valve 282 can be set in the second cavity 100b, wherein one end of the second solenoid valve 282 is connected to the return water port of the gas-liquid separator 220 through a pipeline. When a large amount of water is stored in the gas-liquid separator 220, the second solenoid valve 282 can be controlled to operate to circulate the water to the pure water tank 230.

The above-mentioned specific implementation methods are merely illustrative and not restrictive.
