Hydrolysis hydrogen production aluminum substrate and preparation method

Abstract

The invention discloses a hydrolysis hydrogen production aluminum substrate. The hydrolysis hydrogen production aluminum substrate is characterized in that an aluminum substrate alloy is formed by melting a plurality of elemental metals and comprises the following components in percentage by weight: 0.02-0.10% of magnesium, 0.2-1.0% of gallium, 0.1-0.80% of indium, 0.02-0.10% of tin, 0.02-0.10% ofbismuth and the balance aluminum and inevitable impurities. The invention further discloses a preparation method of the hydrolysis hydrogen production aluminum substrate. The hydrolysis hydrogen production aluminum substrate is formed by melting the elemental metals without the need for grinding the elemental metals into powder, so that the process of a hydrogen production base material is simplified, and the preparation time of an aluminum alloy is shortened; and the content of trace elements is greatly reduced, so that the preparation cost of the aluminum alloy is favorably reduced.

Description

technical field [0001] The invention relates to an aluminum alloy plate, in particular to an aluminum alloy plate capable of producing hydrogen Background technique [0002] Hydrogen is currently the most environmentally friendly clean energy in the world. The traditional hydrogen production methods include electrolysis of water, fossil hydrogen production and biological hydrogen production. Hydrogen production by electrolysis of water requires a large amount of electricity. Fossil fuel hydrogen production process consumes fossil fuel and produces CO, CO 2 and other by-products pollute the environment. Although the cost of biological hydrogen production is low and the environmental benefits are good, scientists from all over the world attach great importance to it, but the stability and continuity of the hydrogen production process. The above traditional hydrogen production has been restricting the development of hydrogen production. [0003] The use of aluminum alloys f...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned patent documents for producing hydrogen-producing aluminum alloys, there is generally a deficiency that the production process is cumbersome. At the same time, more trace elements are added and the content is relatively large, resulting in high production costs. In the early stage of hydrogen production, the hydrogen gas comes out violently and is not stable enough, and the hydrogen production per unit time varies greatly. Therefore, large-scale industrial production is impossible, which seriously restricts the development and application of hydrogen fuel cells.
