Description

technical field

[0001] The invention belongs to the technical field of preparation of hydrogen storage materials, and in particular relates to an aluminum-containing composite hydrogen storage alloy made based on an aluminum material combined with a hydrogen storage alloy, a preparation method of an aluminum-containing composite hydrogen storage alloy, and a preparation method using the aluminum-containing composite hydrogen storage alloy A composite solid-state hydrogen storage tank and a method for testing the hydrogen storage performance of the composite solid-state hydrogen storage tank. Background technique

[0002] The depletion of fossil energy and the crisis of environmental pollution force human beings to develop renewable and clean energy. Hydrogen is a clean secondary energy and an ideal carrier of renewable primary energy. In the 1970s, General Motors of the United States put forward the concept of "hydrogen economy era" to describe the future where hydrogen wil...
