Abstract
This demonstration brings the simplest multidisciplinary approach to evaluate the impact of the electrocatalysts in the water electrolysis half-reactions. The experiment is implemented with damaged hard drive (HD) platters as dimensionally stable electrodes for hydrogen and oxygen evolution reactions. The CoPtCr and Ni
