Abstract:
We study slow and nearly reversible processes of reduction, hydride formation and oxidation in Raney-Ni air electrodes in concentrated
KOH solutions. A labile ?-NiH phase is formed upon
prolonged cathodic polarization under H2 atmosphere. Repeated cathodic/anodic cycles enhance hydrogen intake and induce surface
modifications of the Raney-Ni grains.
