Description

technical field [0001] The invention belongs to the field of hydrogen preparation and storage equipment, and in particular relates to an integrated hydrogen supply device. Background technique [0002] Hydrogen energy is a clean and efficient energy carrier. The large-scale application of hydrogen energy must solve the three related technologies of hydrogen production, storage, transportation and application. At present, hydrogen production and hydrogen storage are separated separately. Usually, the hydrogen produced in the hydrogen production equipment is placed in a gas storage tank, and then compressed into a gas storage bottle. Hydrogen is mostly used as fuel or raw material in high-pressure gaseous form. Although the high-pressure hydrogen storage technology is relatively mature and the equipment structure is relatively simple, there are still certain difficulties in long-distance transmission, which also increases the cost of users. The density of hydrogen is small, ...

AI Technical Summary

Problems solved by technology

Hydrogen is mostly used as fuel or raw material in high-pressure gaseous form. Although the high-pressure hydrogen storage technology is relatively mature and the equipment structure is relatively simple, there are still certain difficulties in long-distance transmission, which also increases the cost of users.

Low density of hydrogen gas, liquid hydrogen storage and gaseous hydrogen storage, low efficiency and high cost

Much exploration has been done in the field of solid-state hydrogen storage, but hydrogen sources are not readily available

In the field of hydrogen production by hydrolysis, people have done a lot of research, but the reaction is too violent, it is inconvenient to control, and it is impossible to supply hydrogen sustainably

In the patent with the publication number CN101877411A, although a hydrolysis hydrogen supply device is designed, the internal solid fuel will suck out the liquid in the water-absorbing material to avoid excessive reaction, but the hydrogen supply rate cannot be reliably controlled, and the hydrophilicity of the solid fuel is lower than that of the water-absorbing material Water absorption, can not guarantee the sustainable hydrogen production reaction of hydrolysis

The publication number is CN201158714Y patent, which provides a mobile hydrolysis aluminum hydrogen production device. Using a hydrogen device to supply hydrogen, the assembly is too complicated

Hydrogen production, hydrogen storage, and purification are composed of three parts, which are inconvenient to carry

The publication number is CN102212838A invention patent, which realizes the integrated device of hydrogen production and storage by electrolysis of water, but the separation of hydrogen and oxygen and the purification of hydrogen are not involved, and the purity of directly produced hydrogen cannot meet the working requirements of fuel cells, and electrolysis The hydrogen production device consumes electric energy, and in terms of energy efficiency, it cannot achieve the goal of high efficiency and economy

After searching, no integrated device has been found that integrates the hydrolysis hydrogen production device and the hydrogen supply device. At the same time, it can solve the problem of severe reaction of the hydrolysis hydrogen production device and inconvenient control, and the problem that the hydrogen source required by the hydrogen storage device cannot be met immediately.
