Abstract

The invention provides a solid hydrogen storage device. A cylinder is internally connected with a heat conductive sheet; a hydrogen inlet valve and a hydrogen outlet valve are respectively connected with the exteriors of the two ends of the cylinder; a filter passes through the central hole of the heat conductive sheet; two ends of the filter are respectively connected with the hydrogen inlet valve and the hydrogen outlet valve; the cylinder is internally provided with a snake-shaped water circulation pipe which is arranged longitudinally along the cylinder and is connected with the heat conductive sheet; the heat conductive sheet is connected with a sheet-shaped crossing. Large holes are uniformly distributed along 2 / 3 of the radius of the heat conductive sheet; small holes are uniformly distributed along 1 / 3 of the radius of the heat conductive sheet; the sheet-shaped crossing is horizontally arranged between the large holes and the small holes of the heat conductive sheet; the snake-shaped water circulation pipeline passes through the heat conductive sheet and deviously passes through the large holes in 120 DEG on the heat conductive sheet with an arc ranging from 30-90 DEG; the water outlet and the water inlet of the snake-shaped water circulation pipe are respectively arranged at the end plates of the two ends of the cylinder.

Description

Technical field: [0001] The invention relates to a hydrogen storage device, in particular to a hydrogen storage device filled with a metal hydride hydrogen storage alloy material. Background technique: [0002] Hydrogen energy has many advantages such as cleanliness, high efficiency, and regeneration, and is a new type of energy that has attracted widespread attention. Transportation consumes a lot of energy. Around the development and application of hydrogen, relevant experts have done a lot of research on the three methods of low-temperature liquid hydrogen storage, high-pressure gaseous hydrogen storage and solid hydrogen storage. Although low-temperature liquid hydrogen storage is convenient for storage and transportation, However, the liquefaction cost of hydrogen is too high, which greatly increases the cost of hydrogen energy, high energy consumption, and easy leakage; for high-pressure hydrogen storage, although the pressure can be as high as 70MPa or more, the densi...
