The anodic dissolution and passivation of vertical porous zinc electrodes that were prepared by pressing zinc powder or amalgamated zinc powder into small disks were studied in 6 M KOH + O-25 M ZnO by measuring potentiostatic current/potential curves at a rate of 1 mV/s and by taking photomicrograph
