This patent describes a bi-polar nickel-hydrogen battery. This battery consits of: (a) a pressure vessel containing hydrogen gas; and (b) unit cells located within the pressure vessel, the unit cells being stacked adjacent one another for axial current flow. Each unit cell consists of (1) walls defining a unit space; (2) a hydrogen electrode located within the cell space; (3) a nickel electrode located within the cell space having at least one opening extending therethrough to facilitate oxygen recombination by allowing oxygen gas evolved at the nickel electrode to reach the hydrogen electrode for recombination with hydrogen gas thereat to form water within the unit cell space and to prevent O/sub 2/ migration outside of the unit cell; (4) a separator disposed between the nickel and hydrogen electrodes within the cell space having means for allowing oxygen gas evolved at the nickel electrode to reach the hydrogen electrode for recombination with hydrogen gas thereat and cooperating with the nickel electrode in preventing O/sub 2/ migration outside of the unit cell; and (5) an electrolyte located in the cell space about the nickel and hydrogen electrodes and the separator to permit an electrochemical reaction between the nickel and hydrogen electrodes.
