Material composition for use in hydrogen storage structure, material for use in hydrogen storage structure, and hydrogen storage single tube

Abstract

Provided is a material for use in a hydrogen storage structure, a hydrogen storage single tube, and a material composition for a hydrogen storage structure used for the preparation of the material for use in the hydrogen storage structure and the hydrogen storage single tube. The hydrogen storage single tube is provided with a honeycomb-shaped high pressure hydrogen storage structure with a micron-sized pore diameter and is lightweight. A hydrogen storage structure having a pore diameter of 150 μm and a pipe wall thickness of 35 μm has an ultimate pressure of >200 MPa, a Rockwell hardness of 86-89, a high temperature resistance of >1900° C., a low temperature resistance of <−260° C., low thermal conductivity, high temperature thermal insulation, and strong acid and alkali resistance. In a high density hydrogen work atmosphere and a complicated dynamic environment, the high pressure hydrogen storage structure is very stable.
