Hydrogen production method and device of non-electric heating quick-start hydrogen storage material

Abstract

The invention relates to a hydrogen production method and device of a non-electric heating quick-start hydrogen storage material. The method comprises the following steps that reaction powder A and water or an aqueous solution are subjected to exothermic reaction, heat generated by the exothermic reaction makes the water or the aqueous solution generate vapor, and the generated vapor and reactionpowder B are in contact and start the hydrogen storage material for hydrogen production reaction; the corresponding device comprises a hollow shell, wherein the shell is internally provided with a layer of separation net, the separation net divides an internal 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 conveys water to the reaction powder A storage chamber and the reaction powder B storage chamber through an inflow distributing pipe, and a water supply assembly communicated with the water inlet is arranged outside the shell. The hydrogen production device of the non-electric heating quick-start hydrogen storage material has the advantages that in a non-electric heating state, the device can enable the water to be transformed into the vapor through the exothermic reaction of the reaction powder A in the device, the vapor is in contact with the reaction powder B to promote fast starting of the hydrogen production reaction, 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. ...
