Study on Hydrogen Generation from Al−Li/NaBH₄ Mixture in Pure Water for Portable Fuel Cell

Abstract:

Solid-state Al−Li/NaBH₄ mixtures with salts have been fabricated for hydrogen evolution through a milling process, providing uniform dispersion of metals Al, Li and salts among pulverized NaBH₄particles, in order to increase the contacts of NaBH4 with active catalytic sites. The results show that the mixture has good hydrolysis properties, especially that Al−Li−CoCl₂/NaBH₄ mixture has hydrogen yield of 1482 mL g^-1 in 40−minute hydrolysis in pure water, with 100% conversion efficiency. The catalytic effect comes from Al(OH)₃and Ni₂B or Co₂B, which were fabricated in the hydrolysis process.
