Operational and structural variables affecting the performance of sintered iron electrodes were investigated. The porosity of the electrode is the predominant controlling factor, and surface area and neck-width after sintering, as well as solid phase conductivity, are also important. A recommended sintering condition is 800~ for 0.5 hr. The discharge products were also identified by means of x-ray diffraction and scanning electron microscopy to be Fe(OH)2 at the first discharge stage and Fe304 at the second stage. Finally a dimensionless group was proposed to estimate the capacity of an iron electrode.
