Abstract

The invention provides an aluminum alloy for hydrogen production and a preparation method of the aluminum alloy, and belongs to the technical field of hydrogen production materials. The aluminum alloycomprises the following ingredients by weight percentage: 90-99.9% of aluminum and 0.1-10% of other metals, wherein the other metals comprise one or more of lanthanum, lithium, gallium, molybdenum, lead, tin, zinc, antimony, titanium, indium, bismuth, manganese, nickel, cadmium, strontium, magnesium and calcium. The activity of an aluminum metal is improved, and a too sharp reaction can be prevented by adding the other metals, and the aluminum alloy can react with water mildly at ordinary temperature to generate hydrogen.

Description

technical field [0001] The invention relates to the technical field of hydrogen production materials, in particular to an aluminum alloy for hydrogen production and a preparation method thereof. Background technique [0002] Hydrogen energy, as a clean energy source, has attracted much attention. It is converted into electrical energy in a hydrogen fuel cell, and its product is water. However, the difficulty in supplying hydrogen has become a technical difficulty restricting the promotion of hydrogen fuel cells. Metal aluminum reacts with water to produce hydrogen, but the reaction is extremely slow. In order to increase the reaction rate, a certain amount of lithium is currently mainly added to metal aluminum. However, the content of active metals in aluminum-lithium alloys is relatively high, and the reaction with water is violent and dangerous. higher. Contents of the invention [0003] The object of the present invention is to provide an aluminum alloy for hydrogen p...
