▎ 摘　　要

NOVELTY - Hydrogen storage composite material comprises a graphene oxide framework configured as a porous structure and having an average pore diameter of 1-2 nm. The graphene oxide is impregnated with a metal hydride. The hydrogen emission temperature is 25-100?oC. The linker includes a diboronic acid, and the graphene oxide has a hydrophobic surface. The material is formed by adding graphene oxide to a solvent and ultrasonic grinding, and forming a framework by providing a linker on graphene oxide, and supporting metal hydride on the framework. USE - Hydrogen storage composite material used in an energy system including domestic and industrial fuel cells, and in a polymer electrolyte fuel cell. ADVANTAGE - The hydrogen storage composite material has excellent hydrogen storage performance by combining metal hydride, and can replace a high-pressure hydrogen storage tank. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing hydrogen storage composite material, which involves adding graphene oxide to a solvent under ultrasonic grinding, forming a graphene oxide framework by providing a linker on the graphene oxide, and supporting metal hydride on the graphene oxide framework.
