Aluminum is one of the most versatile materials for dynamic global economy due to its mechanical properties, recyclability, and lightweight. The production hydrogen from aluminum via hydrolysis in alkaline media offers another advantage it. Recycling post-consumer scraps leads formation some undesirable intermetallic particles which are not only detrimental properties but also repeated recycling. In this study, performance a recycled alloy was compared with that primarily produced one. results showed Mg solutes at grain boundaries (GBs), Fe-containing Mg2Si particles, stress concentration around GBs, thickness passive layer can affect generation rate specimens. specimens were tested proton-exchange membrane fuel cell evaluate their performance. increase yield significantly increases power PEMFC.
