Graphene hydrogen storage device and control method thereof

Abstract

According to the graphene hydrogen storage device, a hydrogen filling pipe (9) is connected to a graphene hydrogen storage box body (10) in a high-precision welding mode, and an electromagnetic valve switch (8) is used for controlling filling and releasing of hydrogen; the hydrogen flow meter (7) is used for monitoring the total flow of hydrogen filling and releasing in real time; the electric field plates (12) are installed on the front side and the rear side of the graphene hydrogen storage box body (10), and the electric field positive electrode (4) of the box body and the electric field negative electrode (14) of the box body are installed on the electric field plates (12) of the graphene hydrogen storage box body (10) respectively and used for being connected with the power source positive electrode (2) and the power source negative electrode (1) of the power source (3). The heating devices are mounted at the left end and the right end of the graphene hydrogen storage box body (10). According to the device, in the hydrogen filling and storing process, an electric field is applied to the two ends of the graphene box body so as to reduce the surface energy barrier of graphene in the box body, and it is guaranteed that hydrogen is compactly adsorbed in the graphene thin layer space.

Description

technical field [0001] The invention relates to a hydrogen storage technology, in particular to a graphene hydrogen storage device and a control method thereof. Background technique [0002] Hydrogen is the most promising clean fuel in the 21st century. Whether it releases energy through electrochemical reaction or combustion, the product is water without any pollution and carbon emissions. [0003] At present, hydrogen involves hydrogen production, storage, transportation and terminal consumption. There are many sources of hydrogen production in my country, including renewable energy electrolysis of water to produce hydrogen, chemical by-product hydrogen, and biomass hydrogen production. [0004] However, one of the important reasons restricting the development of hydrogen is the difficulty of storage and transportation. Although there are currently 35MPa and 70MPa high-pressure gaseous hydrogen storage, hydrogen storage density is low and energy consumption is high; in ad...

[0004] However, one of the important reasons restricting the development of hydrogen is the difficulty of storage and transportation. Although there are currently 35MPa and 70MPa high-pressure gaseous hydrogen storage, hydrogen storage density is low and energy consumption is high; in addition, liquid hydrogen storage can increase hydrogen storage density, However, the temperature of hydrogen must be lowered to -253°C, which will consume about one-third of the energy, high energy consumption, and low economic efficiency; organic hydrogen storage is also a way, but it affects the purity of hydrogen and contains toxic substances; metal hydrogen storage It is a promising method, but it has not yet been applied in large quantities and is still in the research stage
