Hydrogen Production via Alkaline Water Electrolysis Using Cathode Elaborated by Zinc-Manganese Alloy

The development of low-cost materials for hydrogen production is essential for the widespread adoption of sustainable energy technologies. This study demonstrates the viability of low-cost Zn95%Mn5% alloy cathodes, synthesized via sintering, for efficient alkaline water electrolysis. XRD analysis confirmed mixed oxide phases (Zn 1−x Mn x O, MnO x ), while SEM/EDS revealed a homogeneous particle morphology with non-uniform Zn/Mn/O distribution. Electrolysis tests under variable conditions showed a direct correlation between elevated temperature and enhanced hydrogen production rates. These findings underscore the potential of Zn-Mn alloys as sustainable, scalable materials for green hydrogen generation
