An alloy on the base of Al and the (Ga, In, Sn) additive compound (95% Al and 5% (Ga,In,Sn)) was considered in the work. It was established that a low deviation from the (3:1:1) ratio of the (Ga, In, Sn) amount didn't matter in the alloy chemical activity. The technology of the alloy obtaining was major. It was shown that the double (iterative) annealing led to the creation of a finely porous structure with a substantially developed area of surface. It ensured the extremely high efficiency of the hydrogen output.
