Özet

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.
