Abstract

The development of an aluminum metal hydride reactor using additive manufacturing offers a significant innovation in hydrogen storage systems. In this study, reactors with 3 different geometries (Body Centered, Bipyramid, Face Centered Lattice) were produced separately from AlSi10Mg and Ti6Al4V materials with complex geometries by additive manufacturing method and their hydrogen charge/discharge performances were tested in laboratory environment. By using lattice structures in the reactor, heat transfer was improved and hydrogen filling times were shortened. The best result in terms of uniform temperature change and hydrogen storage mass in the reactor produced by additive manufacturing method was given by Bipyramid geometry produced from Ti6Al4V composite material. Measurement of stored hydrogen masses was carried out on a precision balance depending on time. 0.70 gr hydrogen was stored in the reactor.

增材制造方法制备的不同晶格结构反应器储氢性能研究

利用增材制造技术开发的铝金属氢化物反应器为储氢系统提供了重大创新。本研究以AlSi10Mg和Ti6Al4V复合几何材料为原料，采用增材制造方法分别制备了3种不同几何形状（体心、双金字塔、面心点阵）的反应器，并在实验室环境下测试了它们的氢气充放电性能。在反应器中采用点阵结构，改善了传热，缩短了充氢时间。以Ti6Al4V复合材料为材料，采用双棱锥结构制备的增材制造反应器在均匀温度变化和储氢质量方面效果最好。储存氢质量的测量是在一个精确的天平上进行的，这取决于时间。反应器中储存了0.70克氢气。

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
