This study evaluated hydrogen generation through the hydrolysis of an Al/NaBH4/Co/NaAlO2 system. Hydrogen generation performance can be altered by changing the Al/NaBH4 mass ratios, Co amount and NaAlO2 concentration. The optimized composite can achieve a hydrogen yield of more than 90% within...

Hydrogen generation performance of solid-state AlLi/NaBH4 mixture activated by CoCl2 solution was evaluated in the present work. Hydrogen generation performance can be regulated by AlLi/NaBH4 weight ratio, Li content, CoCl2 concentration, and hydrolysis temperature, among others. 1 g Al-20 wt%...

A new process to obtain hydrogen from highly activated Al–Li–Bi alloys in water is described. The alloys had good hydrolytic properties at 298 K, and the optimized composite yielded 1340 mL hydrogen/g Al with 100% efficiency and achieved a maximum hydrogen generation rate of 988 mL/min g...

A systematic investigation of hydrogen production from milled Al–Sn–Zn–X (X: hydride or halide) mixtures in pure water was performed at room temperature. The hydrolysis mechanism of the mixtures was based on the work of micro-galvanic cell between aluminum and tin in water where aluminum...

The hydrogen storage performance of MgH2–10 wt.% TiC composite was investigated. The additive TiC nanoparticle led to a pronounced improvement in the de/hydrogenation kinetics of MgH2. The composite could dehydrogenate 6.3 wt.% at 573 K while the milled MgH2 only released 4.9 wt.% of...

An experiment assessment of hydrogen production from activated aluminum alloy in portable hydrogen generator for fuel cell applications was investigated. The optimum hydrogen capacity of the high–reactive Al–Bi–NaCl alloys (the abbreviation of milled material of aluminum, bismuth and NaCl...

A safe and environmental-friendly method of hydrogen production from milled Al–In–Zn–salt mixture in water was proposed in this paper. The 10 h—milled Al–In–Zn–salt mixture had high reactivity and produced hydrogen in water at room temperature. Its improved reactivity came from...
