Abstract

The invention discloses a metal hydride hydrogen storage tank. The metal hydride hydrogen storage tank comprises a tank body, a flange cover, a heat exchange pipe and cooling fins, wherein a storage cavity is formed inside the tank body, a storage groove is formed in the side wall of the storage cavity, the storage groove is filled with a composite phase change material, the flange cover is hermetically connected to a port of the tank body, a hydrogen inlet / outlet is formed in the flange cover and communicates with the storage cavity, the heat exchange pipe is arranged in the storage cavity, the input end and the output end of the heat exchange pipe communicate with the outside of the flange cover, the number of the cooling fins is multiple, the multiple cooling fins are arranged at intervals along arrangement track of the heat exchange pipe, and hydrogen storage materials are placed between the adjacent cooling fins. Therefore, heat management of the first stage is achieved through arrangement of the composite phase change material, heat management of the second stage is achieved through the heat exchange pipe, namely, the heat management efficiency is improved through different heat management modes, and the problem that an existing hydrogen storage tank is poor in heat management effect is solved.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage, in particular to a metal hydride hydrogen storage tank. Background technique [0002] As a green renewable secondary energy source, hydrogen energy can be used as an energy carrier in modern renewable energy systems, such as wind energy and solar energy, to solve intermittent problems in its operation. As a fuel, hydrogen can be converted to hydrogen electricity or hydrogen heat through fuel cells or internal combustion engines. However, the safe and efficient storage technology of hydrogen has become one of the bottlenecks for its large-scale application. Compared with gaseous hydrogen storage and liquid hydrogen storage methods, the solid-state hydrogen storage method represented by metal hydride hydrogen storage materials has great development prospects due to its advantages of large volume hydrogen storage capacity and high safety. However, since the hydrogen absorption and desorpt...
