Description

technical field [0001] The invention relates to the technical field of metal aluminum fuel energy storage and utilization, in particular to a test system and method for hydrogen production by metal aluminum-water reaction. Background technique [0002] Facing the severe situation of depletion of fossil fuels, the comprehensive utilization of renewable energy has attracted attention. Among them, hydrogen fuel has high chemical energy, and its combustion products are non-toxic and environmentally friendly. It is a promising substitute for fossil fuels. However, the production cost of hydrogen is relatively high. Hydrogen production through metal aluminum-water reaction has been a research hotspot in recent years, and metal aluminum-water hydrogen production can be directly produced when needed, avoiding the safety problems of hydrogen storage and transportation. [0003] Many studies at home and abroad focus on the combustion characteristics of aluminum powder in different at...
