Developing of stand-alone hydrogen generator (AGV) based on the chemical decomposition of water in heterogeneous compositions containing finely dispersed powder aluminum and crystalline sodium metasilicate. The kinetics of accumulation of hydrogen depends on the presence in the reaction medium of oxygen, which is manifested in the presence of an induction period. The nature of the kinetic regularities of hydrogen in the presence of oxygen significantly depends on the ratio of reaction rates, oxidation and activation of the aluminium surface. The design of the AGV and the optimal composition of heterogeneous compositions allow to obtain the theoretically maximum hydrogen yield (0.12 kg per 1 kg of aluminum) at a rate of from 0.01 to 1.5 l/min, at a flow rate of 0.01 to 0.1 m3/h and a duration of generation from 0.1 to 12 hours. AGV in an environmentally safe and energy-saving mode allows to get pure hydrogen fuel hydrogen content 98%, carbon dioxide ~ 0.03 % of carbon monoxide ~ 5⋅10–5 %. All chemical ingredients to produce hydrogen by AGV are chemically safe and stored under normal conditions for a long time. The wide availability of chemicals allows to consider designed AGV as lane-looking source of hydrogen for different consumers. Production of hydrogen using AGV has a number of technical, economic, environmental and social advantages compared with other methods of producing hydrogen when considering the level of integration costs for the implementation of all hydrogen technological chain: production, storage, transportation, distribution and final consumption.
