Description

Electrolytic system package of household hydrogen production equipment

Technical Field

The utility model relates to the field of hydrogen production devices, in particular to the packaging of an electrolytic system of household hydrogen production equipment.

Background

The electrolytic system of the household hydrogen production equipment has different specifications according to different actual hydrogen production equipment. In the prior art, for a given hydrogen production efficiency, it is necessary to configure a separate electrolyzer for a particular hydrogen production plant. Thus, when the product is replaced, a new electrolytic structure needs to be designed again. In the prior art, there are also technologies for using a plurality of electrolyzers, for example, in patent CN202021731106.6 patent "a hydrogen generator by water electrolysis for hydrogen machine", the structure is designed as follows: a water tank and more than one electrolysis device; the electrolytic device comprises an end cover, a first sealing gasket, a cathode electrode, a second sealing gasket, a first breathable gasket, a solid electrolyte, a second breathable gasket, a third sealing gasket and an anode electrode; through grooves are formed in the two sides of the water tank; the anode electrodes are all arranged on the outer sides of the through grooves; the third sealing gaskets 8 are all arranged on the outer side surface of the anode electrode, and the second breathable gaskets are all arranged inside the third sealing gaskets; the solid electrolyte is arranged on the outer side surface of the second breathable pad; the other side of the solid electrolyte is provided with a second sealing gasket; first ventilative pad is all installed inside the sealed pad of second, and the negative electrode is all installed on the lateral surface of first sealed pad, and first sealed pad and end cover are all connected to the negative electrode opposite side.

By such a structure, electrolysis can be performed by a single electrolysis device or two electrolysis devices. However, due to the structural limitation, only 2 electrolyzers can be used at the same time. This does not satisfy the various hydrogen production requirements.

Disclosure of Invention

The technical problem solved by the electrolytic system package of the household hydrogen production equipment is as follows: an expandable electrolytic cell is designed, minimum hydrogen production is carried out through a main electric de-encapsulation module, and the hydrogen production capacity of the whole equipment is adjusted by adding a plurality of expanded electrolytic encapsulation modules.

In order to achieve the purpose, the electrolytic system package of the household hydrogen production equipment at least comprises a main electric de-encapsulation module and a plurality of extended electrolytic encapsulation modules; the electrolytic cell is characterized in that a conventional PEM electrolytic structure is arranged in the main electric deblocking module, the conventional PEM electrolytic structure is arranged in an independent electrolytic cell and is arranged at one end of the electrolytic cell, a plurality of groups of triangular columnar positioning columns are further arranged in the electrolytic cell, the expanded electrolytic encapsulation module is inserted between two adjacent positioning columns, and the electrode plate in the expanded electric deblocking module is electrically connected to an electric loop of the main electrolytic encapsulation module in the electrolytic cell.

Preferably, the bottom of the electrolytic cell is provided with a liquid channel, and the top of the electrolytic cell is provided with a gas channel. This achieves the effect of gas-liquid separation.

Preferably, the expanded electrolytic packaging module comprises electrolytic modules arranged in the packaging box body, each electrolytic module comprises an electrode plate and a modified thin film layer between adjacent electrode plates, and a catalytic layer and a diffusion layer are arranged between the electrode plates and the modified thin film layers; the modified film layer is a titanium gold nano composite film layer plated with fluoropolymer on the surface. The whole volume of the expanded electrolytic packaging module is small, and the proton exchange membrane is adopted as a catalyst carrier, so that the conversion efficiency of hydrogen is effectively improved.

Preferably, the structure of the packaging box body of each expanded electrolytic packaging module is the same, and the number of the electrode plates arranged in the packaging box body is 3-5. Although the structure of the packaging box body of each expanded electrolytic packaging module is the same, the number and the size of the electrode plates installed in the packaging box body are adjusted according to the actual hydrogen production amount, and the number and the size of the electrode plates in the packaging box body of each expanded electrolytic packaging module are different.

Preferably, the electrode plate is a stainless steel plate or a titanium plate with the thickness of 0.5mm-1.0 mm. The metal electrode plate with the structure can ensure the hydrogen production effect and the service life.

Preferably, the liquid flowing through the electrolytic cell is pure water. Because the device is a household hydrogen production device, the hydrogen production by adopting pure water does not produce additional pollution.

Preferably, the number of the positioning columns is 3-5. If the number of the positioning columns is too small, the expansion capability is limited, and if the number of the positioning columns is too large, the volume of the electrolytic bath is too large, and the cost is too high when the electrolytic bath is used as a basic structure.

The electrolytic system package of the household hydrogen production equipment has the advantages that: when an electrolysis equipment supplier prepares devices with different hydrogen production effects, the hydrogen production capacity can be improved as required only by designing an additional expanded electrolysis encapsulation module on a basic main electricity decapsulation module. Therefore, the generation die does not need to be replaced when the product is replaced, the production cost is reduced, and the standardized production is facilitated.
