Abstract
A nickel-hydrogen bipolar battery comprises a plurality of unit cells organized in assemblies wherein the assemblies are stacked and positioned within a hydrogen space. Each unit cell includes a porous hydrogen electrode loaded on its lower surface with a platinum catalyst layer. Adjacent the platinum loaded lower surface of the porous hydrogen electrode lies a separator. A nickel electrode lies against the separator opposite the surface adjacent to the platinum loaded surface. One or more openings through the nickel electrode and separator cooperate to permit oxygen gas, generated at the nickel electrode, to reach to the hydrogen electrode of the same unit cell. Recombination of hydrogen gas and oxygen gas occurs at the hydrogen electrode platinum catalyst layer. The assembly provides serial connection of the unit cells through conductive end plates for axial current flow through the assembly stack.
