Problems solved by technology

However, it is difficult to realize automatic control of this process, which is a naturally changing process. For example, during the exothermic process of hydrogenation, when the temperature of the phase change material becomes higher, it will affect the hydrogenation effect, and after the strengthening is completed, if the phase change material The temperature of the variable material is still in a high temperature state, which will accelerate the release of hydrogen, which is what people don't want to see
[0005] It can be seen that solid-state hydrogen storage reactors usually have the problems of low heat transfer efficiency and difficulty in automatic control, which have limitations in practical industrial applications.

Abstract

The invention relates to a solid-state hydrogen source reactor, which adopts phase-change materials to recycle and utilize the heat in the solid-state hydrogen storage chemical reaction, and can fill the heat-conducting particles between the particles of the metal hydrogen storage material after mixing the heat-conducting particles with the metal hydrogen-storage material, And the quality of the metal hydrogen storage material per unit volume is not reduced. At the same time, due to the high thermal conductivity of the heat-conducting particles, the rapid heat conduction of the metal hydrogen storage material gap is realized, and the temperature gradient of the metal hydrogen storage material is reduced. When the heat-conducting medium storage tank is set, the use The temperature detection device detects the temperature to open and close the valve, so that the high-temperature medium does not enter the solid-state hydrogen storage tank during hydrogen absorption, and the low-temperature medium does not enter the phase-change material heat storage tank during dehydrogenation, which further improves heat exchange efficiency and hydrogenation. and hydrogen release stability.

Description

technical field [0001] The invention relates to the field of hydrogen power, in particular to a solid-state hydrogen source reactor. Background technique [0002] The massive use of fossil fuels not only aggravates the consumption of traditional energy, but also causes serious pollution to the environment. Hydrogen has abundant reserves and high combustion calorific value, and the pollution caused by the combustion products to the environment is extremely weak. However, the main limitation of the large-scale application of hydrogen is that the hydrogen storage technology is immature, and it is difficult to store and transport hydrogen quickly, safely and efficiently. At present, there are mainly three types of hydrogen storage methods: high-pressure gas hydrogen storage, low-temperature liquid hydrogen storage and solid hydrogen storage. Solid hydrogen storage, especially metal hydrogen storage materials, is regarded as one of the most promising hydrogen storage materials ...
