Description

Technical Field

[0001] The utility model relates to the field of hydrogen production and storage devices, in particular to a mobile PEM hydrogen production and storage device. Background Art

[0002] The mobile PEM hydrogen production and storage device is a device that uses proton exchange membrane water electrolysis technology to decompose water into hydrogen and oxygen. It is an easy-to-move device that can be flexibly moved to different locations for use. It is portable and flexible and can be widely used in scenarios that require temporary or mobile hydrogen supply, such as outdoor activities, emergency power supplies, and hydrogen energy vehicle filling stations. Its advantages include efficient energy conversion, pollution-free emissions, and easy operation.

[0003] In actual use, traditional mobile hydrogen production and storage devices mostly only retain the produced hydrogen and choose to discharge oxygen in the open air. However, discharging oxygen in the open air when moving may cause the oxygen to encounter flammable materials, causing a chemical reaction between the oxygen and the flammable materials, which may in turn produce an explosion, reducing the safety of the device when in use. In addition, most traditional mobile hydrogen production and storage devices do not have an air compressor, so uncompressed hydrogen directly entering the hydrogen storage tank will occupy a large volume, thereby reducing the storage space of the hydrogen storage tank, thereby reducing the practicality of the mobile hydrogen production and storage device.

[0004] Therefore, those skilled in the art provide a mobile PEM hydrogen production and storage device to solve the problems raised in the above background technology. Utility Model Content
