Abstract

An efficient heat-accumulated hydrogen accumulator for Mg-base hydrogen-bearing material is a cylindrical body, which is composed of external and internal shells and vacuum layer between them, insulating layer on the inner surface of internal shell, heat accumulating tubes in the insulating layer, heat transfer tube at inside of the most external heat accumulating layer, hydrogen distributing and filtering tube passing through hdyrogen filter layer and installed at central position of internal shell, and hydrogen filter layer installed on supporting plate on the internal shell. It features that the heat generated by absorbing hydrogen is accumulated for supplying it when hydrogen is released.

Description

Technical field: [0001] The invention proposes a regenerative high-efficiency hydrogen storage device for magnesium-based hydrogen storage materials, and the hydrogen storage device can provide hydrogen gas for places requiring hydrogen sources. Background technique: [0002] Although magnesium-based hydrogen storage materials have a wide range of applications, such as purification and separation, heat pumps, constant temperature systems, isotope separation, temperature sensors, fuel cells, etc., from an energy point of view, magnesium-based hydrogen storage Compared with natural gas and gasoline, the cost of materials is still not dominant, and its utilization is also restricted by some factors such as hydrogen absorption and desorption temperature, cycle life, thermal effect and other factors. In a sense, the application research of magnesium-based hydrogen storage materials and its defects in hydrogen charge and discharge performance can be overcome in combination with sp...
