The hydrogen production by reaction of aluminum foils and powders with KOH aqueous alkaline solutions was studied. Effect of different physical factors on the specific hydrogen production rate was analyzed. The efficiency of activation of aluminum by copper was examined. Three variants of contacting copper with aluminum were considered: 1) preliminary chemical coating of the aluminum surface, 2) embedding copper into the melt of aluminum or pressing the aluminum – copper powder mixture, 3) continuous supplying copper to the aluminum surface during the reaction. The results showed that presence of copper on the surface or in the bulk of aluminum essentially increased the effective hydrogen production rate. The filtration corrosion in pressed aluminum powder was found. Hydrogen production at reaction of aluminum with NaCl + CuSO 4 solutions was studied. [ABSTRACT FROM AUTHOR]
