摘要: Abstract This work presents a parametric investigation of aluminum–water reaction to generate hydrogen, using novel activated aluminum powder. An original thermo-chemical process involving small fraction lithium-based activator enables spontaneous the particles with water, which otherwise would not react due existence an oxide or hydroxide surface layer. Experiments have shown that fast, self sustained water takes place even at room temperature and, for appropriate operating conditions, results in practically 100% yield hydrogen generation. The rate may be controlled by particle size, temperature, metal activation conditions and metal/water mass ratio. method demonstrates safe compact storage (11 wt% compared aluminum). Among its potential applications fuel cells, as well automotive marine propulsion.
