Abstract

The invention relates to a non-electric heating quick start hydrogen storage material hydrogen production method and a device thereof, and the method comprises the following steps: carrying out an exothermic reaction of reaction powder A and water or an aqueous solution, enabling the water or the aqueous solution to generate water vapor through the heat generated by the exothermic reaction, enabling the generated water vapor to be in contact with reaction powder B, and starting the hydrogen storage material hydrogen production reaction; wherein the corresponding device comprises a hollow shell, a layer of separation net is arranged in the shell and divides the inner space of the shell into a reaction powder A storage chamber and a reaction powder B storage chamber, an air outlet and a water inlet are formed in the shell, the air outlet is communicated with the reaction powder B storage chamber, the water inlet supplies water to the reaction powder A storage chamber and the reaction powder B storage chamber through a water inlet distribution pipe, and a water supply assembly communicated with the water inlet is arranged outside the shell. The device has the beneficial effects that water can be converted into water vapor through the exothermic reaction of the reaction powder A in the device in a non-electric heating state, the water vapor is in contact with the reaction powder B,the hydrogen production reaction is promoted to be started quickly, the device is simple, and the hydrogen production efficiency is high.

Description

technical field [0001] The invention belongs to the field of hydrogen fuel cells, and relates to the field of hydrogen production by using powdered hydrogen storage materials, in particular to a method and a device for producing hydrogen from hydrogen storage materials without electric heating and quickly starting. Background technique [0002] Hydrogen energy is abundant in nature, has a high combustion calorific value, is environmentally friendly and renewable after combustion, and is one of the best options to replace traditional fossil energy. Compared with high-pressure gaseous hydrogen storage and low-temperature liquid hydrogen storage, the hydrogen storage capacity of certain metal hydrides is comparable to that of liquefied hydrogen storage, or even higher. In the solid-state hydrogen storage mode, hydrogen is mainly combined with metal elements or compounds in the form of various chemical bonds to form metal hydrides, chemical hydrides, and coordination hydrides. ...
