Mobile hydrogen-generating hydrogen-storing integrated device and hydrogen supplying method thereof

Abstract

The invention relates to a movable integrated device for generation and storage of hydrogen and a hydrogen supply method, which belongs to the hydrogen preparation technical field. The movable integrated device for generation and storage of hydrogen comprises a hydrogen generator and a hydrogen storage tank. The device is characterized in that: the hydrogen generator is connected with a gas-water separator through a pipeline, and the gas-water separator is connected with a hydrogen purifier through a pipeline; the hydrogen purifier is connected with the hydrogen storage tank through a pipeline, and the hydrogen storage tank is provided with a temperature controlling apparatus. The hydrogen supply method is that: chemical reaction happens in the hydrogen generator to produce hydrogen, and the water and the hydrogen are separated by the gas-water separator; then purified by the hydrogen purifier, the hydrogen is stored into the storage tank after temperature regulated; while the hydrogen is needed, the hydrogen storage tank supplies the hydrogen through controlling the temperature. The invention has the advantages of simple structure, low construction cost, reliable technique, safety, high hydrogen generating speed, high purity of the hydrogen, less energy consumption and no pollution, etc., and is particularly applicable to movable situations.

Description

technical field [0001] The invention belongs to the technical field of hydrogen preparation, and in particular relates to a mobile hydrogen production and storage integrated device and a hydrogen supply method thereof. Background technique [0002] As an important chemical substance, hydrogen is widely used in chemical, petroleum, food, metallurgy and other industrial fields. At the same time, hydrogen is also a clean energy material. To realize the large-scale application of hydrogen energy, low-cost hydrogen production technology and safe and efficient hydrogen storage technology are the key. [0003] Many metals or compounds, such as aluminum, zinc, sodium borohydride, sodium hydride, lithium hydride, calcium hydride, etc., can react with water to produce hydrogen gas. Hydrogen can be produced using these reactions: [0004] 2Al+2NaOH+6H 2 O2Na[Al(OH) 4 ]+3H 2 ↑ [0005] 2NaBH 4 +2H 2 O2NaAlO 2 +4H 2 ↑ [0006] 2CaH 2 +2H 2 O2Ca(OH) 2 +2H 2 ↑ [0007] ...

AI Technical Summary

Problems solved by technology

Both the high-pressure hydrogen cylinder method and the low-temperature liquefied hydrogen method have disadvantages such as high cost and poor safety during use and transportation; carbon material adsorption hydrogen storage is still in the research stage

The metal hydride solid-state hydrogen storage method is a simple, cheap, and safe hydrogen storage method. However, in actual operation, the metal hydride hydrogen storage tank needs to be supplemented by a hydrogen source with sufficient pressure before it can be used repeatedly. It is extremely inconvenient for mobile applications.
