Description

Technical Field

[0001] This utility model belongs to the field of hydrogen fuel cell technology, and in particular relates to a hydrogen production device for a cylindrical hydrogen fuel cell. Background Technology

[0002] Currently, on-site water electrolysis for hydrogen production is one of the preferred portable power sources for hydrogen fuel cells. This involves using a hydrogen production device to produce hydrogen in real time, and then delivering the hydrogen to the hydrogen fuel cell via pipelines to generate electricity. However, existing hydrogen production devices have several drawbacks, such as their large size, making them difficult to carry; the use of screws and other connecting structures between the casing and components, hindering easy disassembly and replacement; and the fact that the water tank, hydrogen reactor, and dryer involved in the hydrogen production process are often located in the same space as pumps, batteries, and wiring, posing certain safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide a hydrogen production device for a cylindrical hydrogen fuel cell. The device has a cylindrical shell, which is easy to hold and carry. The interior is divided into spaces by partitions to fix the water tank, hydrogen production reactor and dryer, making the internal structure compact and reducing the overall volume of the hydrogen production device. It also divides the interior of the hydrogen production device into sections, which effectively improves safety.

[0004] To achieve the above objectives, the technical solution of this utility model is to design a hydrogen production device for a cylindrical hydrogen fuel cell, including a cylindrical upper cap and a lower cap; the upper cap and the lower cap are connected by a rotating snap-fit ​​connection; the upper cap is provided with a hydrogen outlet; a partition seat is installed inside the lower cap; the partition seat is composed of a partition and several mounting seats, and the partition at the bottom of the mounting seats is provided with a through hole; a battery and a pump are arranged in the space between the lower cap and the partition seat; a water tank, a hydrogen reactor, and a dryer are respectively installed in the several mounting seats; the battery powers the pump, and the pump's input and output ends are connected to pipelines, which pass through the through holes in the partition seat and are respectively connected to the water tank and the hydrogen reactor; the outlet of the hydrogen reactor is connected to a pipeline, which passes through the through holes in the partition seat and is connected to the dryer, and the dryer is connected to the hydrogen outlet through a pipeline.

[0005] Furthermore, the lower rotating seat is provided with several columns for supporting the partition seat, which can be used to support the partition seat.

[0006] Furthermore, the lower rotating seat has a structure that is wider at the top and narrower at the bottom. This structure facilitates the insertion of the partition seat into the lower rotating seat, and the diameter of the partition seat is slightly smaller than the diameter of the upper part of the lower rotating seat, so that the partition seat can be secured to the inner wall of the lower rotating seat.

[0007] Furthermore, the outer side of the lower rotating seat is also provided with a switch and a charging port. The switch controls the start and stop of the pump, and the charging port is used to connect an external power source to charge the battery.

[0008] Furthermore, the lower rotating seat is also equipped with a pressure regulating plate for controlling the pump flow rate.

[0009] Furthermore, the outer wall of the upper screw cap is provided with several heat dissipation holes.

[0010] The advantages and beneficial effects of this utility model are as follows:

[0011] 1) The cylindrical outer shell is easy to hold and carry, making it highly portable.

[0012] 2) The upper cap and the lower seat are connected by a rotating snap-fit ​​mechanism, which facilitates disassembly, maintenance and replacement of internal parts.

[0013] 3) The partition seat is both a partition and a mounting base. It can be used to separate the interior of the hydrogen production unit, separating the water tank, reactor and dryer involved in hydrogen production from the pump, pressure regulating plate and battery to improve safety. It can also be used to fix the water tank, reactor and dryer. Attached Figure Description
