【Abstract】 The technology of aluminum water electrolysis for hydrogen production has the advantages of high hydrogen storage density,safe and environmentally friendly,becoming one of the hydrogen production technologies with high compatibility and being able to meet the needs of hydrogen supply of fuel cell in special scenes. It is described in this paper that the aluminum matrix composite of 85%Al-9%LiAlH4-3%Bi-3%NaCl is produced with high-energy ball milling process,the hydrogen production performance in different scenes and its safety under special environment are studied,and the stable supply of hydrogen flow is achieved through the design and production of the device of aluminum-water reaction for producing hydrogen. The results show that at a temperature of 50oC,the maximum hydrogen output of aluminum matrix composite,which has a good fire resistance property shown by burning experiment,reaches 1,435 mL/g,and the device designed for aluminum-water reaction can fulfill a stable hydrogen supply with a flow rate of 0.8 L/min,meeting the operation demand of low-power fuel cell.更多还原
