Abstract

Aluminum is of great interest as a hydrogen source because it has a high energy density (8100 Wh.kg−1) and

is a recyclable metal. However, due to the strong passive oxide layer formed on the surface of Al metal, its

high overpotential and rapid depletion due to corrosion cause this metal to not perform fully as a hydrogen

source. To overcome this, the Al content can be changed and/or the ambient conditions where the reaction

takes place can be improved by the alloying method. In this study, the ambient conditions were tried to be

improved by both Al alloying by adding B in different proportions by casting method and hydrolysis

reactions in alkaline solution. Hydrogen production performances of Al alloys obtained by adding trace

amounts of B at different rates were investigated for different temperatures.
