Outline of Final Research Achievements

Following three research programs with respect to high pressure hydrogen production by aluminum (Al) alloy and water (H2O) reaction have been performed
Fine Al powder is highly available for production of hydrogen. Ｈigh pressure hydrogen are possible by use of Al alloy-water reactions. Control of hydrogen production in Al-H2O system is possible by changing the reaction temperature at low temperature-high temperature cycles.　 Cycle of hydrogen production is possible by changing aluminum hydroxide (Al(OH)3)and/or alumina(Al2O3) into aluminum nitride (AlN). The thermal decomposition of AlN into Al metal at considerable high temperature is also available．
