Description

Technical Field

[0001] The invention relates to the technical field of hydrogen energy and fuel cells, and in particular to a solid alloy hydrogen storage device and a hydrogen charging and discharging method thereof. Background Art

[0002] As a green energy and energy carrier with abundant reserves, wide sources and high energy density, hydrogen energy is attracting widespread attention. The development and utilization of hydrogen energy are highly valued by the United States, Japan, Germany, China, Canada and other countries, hoping to enter the era of "hydrogen economy" in the middle of the 21st century. The utilization of hydrogen energy needs to solve the following three problems: hydrogen production, storage and transportation, and application, and the storage and transportation of hydrogen energy is the key to the application of hydrogen energy. Hydrogen exists in gaseous form under normal conditions, and is flammable, explosive and easy to diffuse. In practical applications, people must give priority to safety, efficiency and no leakage loss in hydrogen storage and transportation, which brings great difficulties to storage and transportation. Solid-state storage is to store hydrogen in solid materials by utilizing the physical adsorption or chemical reaction of solids on hydrogen. Solid-state storage can generally be safe, efficient and high-density, and is the most promising research discovery after gaseous storage and liquid storage. Existing solid-state hydrogen storage devices store hydrogen at low temperatures and release hydrogen after heating. However, the heat increased during hydrogen storage due to pressurization reduces the hydrogen storage capacity. When the fuel cell is running at variable loads, different rates of hydrogen are required, and the existing solid-state hydrogen storage cannot effectively control the hydrogen release rate. Summary of the invention

[0003] The purpose of the present invention is to provide a solid alloy hydrogen storage device and a hydrogen charging and discharging method thereof, so as to solve the problem that the hydrogen storage efficiency of the solid hydrogen storage device is affected by temperature and other conditions.

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides the following technical solution: a solid alloy hydrogen storage device and a hydrogen charging and discharging method thereof, comprising an alloy hydrogen storage material container, an electric heating plate, a heat sink, a cooling fan and a solid-state hydrogen storage system controller, wherein the alloy hydrogen storage material container is provided with an electric heating plate inside, a heat sink is provided on the outer surface, and a cooling fan is also provided on one side of the heat sink, and the electric heating plate and the heat sink are electrically connected to the solid-state hydrogen storage system controller.

[0005] Furthermore, the alloy hydrogen storage material container has a built-in aluminum alloy metal partition to prevent the hydrogen storage material from moving back and forth and effectively transfer heat.

[0006] Furthermore, the solid alloy hydrogen storage material container adopts a square design, and can use rare earth, magnesium, titanium, vanadium-based solid solution, and zirconium materials.

[0007] Furthermore, the electric heating plate is inserted into the alloy hydrogen storage material container, and the aluminum alloy metal partition is installed alternately along the electric heating plate and the inner wall of the alloy hydrogen storage material container.

[0008] Furthermore, the heat sink is provided in plurality and evenly distributed on both sides of the solid alloy hydrogen storage material container, and the heat dissipation fan is arranged at the end of the heat sink and dissipates heat along the gap between the heat sinks.

[0009] Furthermore, the solid-state hydrogen storage system controller is also electrically connected to the combined bottle mouth valve and controls its operation.

[0010] Furthermore, the side wall of the alloy hydrogen storage material container is also installed with fixing bolts, and multiple alloy hydrogen storage material containers can be combined through the fixing bracket to meet the total hydrogen storage demand.

[0011] Going further, the specific steps are as follows:

[0012] Hydrogen charging stage: The solid-state hydrogen storage system controller controls the combined bottle mouth valve to open and hydrogen is charged into the alloy hydrogen storage material container. During the hydrogen charging stage, a built-in aluminum alloy metal partition is used to prevent the hydrogen storage material from moving back and forth and effectively transfer heat. The solid-state hydrogen storage system controller also starts the cooling fan to dissipate heat from the heat sink to reduce the temperature rise caused by the hydrogenation process;

[0013] Hydrogen discharge stage: The solid-state hydrogen storage system controller controls the combined bottle mouth valve to open and discharge hydrogen through the hydrogen pipeline. In the hydrogen discharge stage, the solid-state hydrogen storage system controller controls the electric heating plate to heat the inside of the container. The hydrogen expands due to the heat, thereby accelerating the discharge of hydrogen. The solid-state hydrogen storage system controller controls the heating temperature according to the input hydrogen demand, thereby providing sufficient hydrogen. The built-in aluminum alloy metal partition is used to prevent the hydrogen storage material from moving back and forth and effectively transfer heat. After the external hydrogen supply stops, the solid-state hydrogen storage system controller starts the cooling fan to reduce the temperature of the solid-state alloy hydrogen storage material container, thereby reducing the hydrogen release rate, reducing the pressure of the solid-state alloy hydrogen storage material container, and closing the combined bottle mouth valve. Compared with the prior art,

[0014] The beneficial effects of the present invention are as follows: the device is equipped with a heat sink and a heat dissipation fan, and starting the heat dissipation fan during the hydrogen filling stage can effectively reduce the temperature rise caused by the hydrogenation process. The device is equipped with an electric heating plate, and the heating temperature can be controlled according to the amount of hydrogen required during the hydrogen release stage, thereby providing sufficient hydrogen. When the external hydrogen supply is stopped, the heat dissipation fan can be started to reduce the temperature of the hydrogen storage material to reduce the hydrogen release rate of the hydrogen storage material, and reduce the pressure of the hydrogen storage container, thereby increasing the container life.
