Abstract

The invention discloses an aluminum alloy material capable of being used for online hydrogen supply. According to the aluminum alloy material, Al2O3 powder is introduced into an Al-Ga-In-Sn alloy capable of achieving hydrogen generation through hydrolysis to obtain an Al-Ga-In-Sn-Al2O3 alloy, wherein the content of the Al2O3 is not more than 8% by weight; and a fusion casting method is adopted forpreparation. Researches show that an Al2O3 doped aluminum alloy has the good hydrogen production performance, hydrogen can be generated immediately after the alloy is in contact with water, and a reaction does not have delaying time. The Al-Ga-In-Sn-Al2O3 alloy has the stable hydrogen production rate and can be used for online hydrogen supply through hydrolysis, and a stable hydrogen source is provided for proton exchange membrane fuel cells.

Description

technical field [0001] The invention belongs to the field of hydrogen production by hydrolysis of aluminum alloys, and in particular relates to an aluminum alloy material with a stable hydrogen production rate that can be used for online hydrogen supply. Background technique [0002] Hydrogen energy is regarded as the clean energy with the most development potential in the 21st century, especially when combined with the use of fuel cells, the utilization rate of hydrogen energy can be improved. However, the storage of hydrogen is an important technical bottleneck restricting the widespread use of fuel cells. In addition, safety issues and high costs during hydrogen transportation also limit the large-scale use of hydrogen energy. [0003] In order to meet the application requirements of proton exchange membrane fuel cells, the corresponding on-site hydrogen production technology requires raw materials with high hydrogen production capacity and relatively stable hydrogen pro...
