Abstract

The invention discloses a high-pressure hydrogen gas supply device, which comprises a closed hydrogen storage chemical bed filled with an LaNi5 material, an outlet pipeline connected with an inner space of the hydrogen storage chemical bed, a first high pressure valve and a pressure sensor which are arranged on the output pipeline, a heater arranged by wrapping the hydrogen storage chemical bed, and a temperature controller connected with the heater. The hydrogen is stored by adopting a solid hydrogen storage material, a large and bulky steel cylinder for storing high-pressure hydrogen gas is not needed, and the extremely low temperature conditions for the storage of liquid hydrogen are not needed; when the hydrogen needs to be stored, an alloy is reacted with hydrogen to produce a metal hydride and heat is released; when the hydrogen needs to be used, the hydrogen stored in the solid hydrogen storage material is released by heating or decompression.

Description

technical field [0001] The invention relates to a high-pressure hydrogen gas supply device, a manufacturing method and a using method thereof. Background technique [0002] Hydrogen is an extremely flammable, colorless and transparent gas. The density of hydrogen is very small, only 1 / 14 of that of air. Hydrogen is the substance with the smallest relative molecular mass. The special physical and chemical properties of hydrogen determine that hydrogen has extensive and special uses. In life, hydrogen can be used as a light medium to fill balloons to make them fly. In industry, it can be used as a high-energy fuel and as a propellant for power rockets. Moreover, hydrogen is also an important chemical raw material for the synthesis of ammonia industry. With the development of new technologies, the application of hydrogen will be more extensive and important. [0003] With the different uses of hydrogen, the technical requirements for hydrogen are also different, such as hydro...
