Abstract

The invention discloses a high-pressure hydrogen storage method and a gas cylinder, the gas cylinder comprises a plurality of hydrogen storage capillary tubes for storing hydrogen, a metal organic framework adsorption material and a covalent organic compound adsorption material are sequentially synthesized in situ in each hydrogen storage capillary tube, and the plurality of hydrogen storage capillary tubes form a capillary tube bundle; external compressed hydrogen is introduced from one end of the capillary tube bundle, and the hydrogen is stored in each hydrogen storage capillary tube in the capillary tube bundle. The integrated low-density capillary tube bundle filled with the metal organic framework adsorption material and the covalent organic compound adsorption material in situ at the same time is adopted for hydrogen storage, the hydrogen storage pressure is high, the hydrogen storage capacity is high, the manufacturing cost is low, high-pressure hydrogen is stored in a relatively light container, and the high commercial application value is achieved.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage, in particular to a high-pressure hydrogen storage method and a gas cylinder. Background technique [0002] Hydrogen storage is a key challenge in the development of hydrogen energy applications. Two main goals drove improvements to cylinders. First, H must be lowered 2 transportation costs. For example, the total capital and operating costs of tube trailers make up a major portion of the price of delivered hydrogen. Second, the functional requirements of the hydrogen energy system must be met, such as weight and volume density sufficient to match hydrogen fuel cell vehicles with equivalent gasoline vehicles. [0003] For many years, cylinders have been the most widely used compressed hydrogen, gas storage technology. It offers relatively low weight and volumetric storage densities. Alternatives to cylinders include liquid H 2 tanks, composite compressed hydrogen tanks, gas storage...
