Bipolar battery design concepts developed by Hughes and NASA's Lewis Research Center have been described in previous publications. In the Hughes version of the design, shown schematically in Figure 1, electrolyte is contained inside each unit cell by integrating cell components in an insulated hydrophobic frame. Oxygen recombination sites are provided behind each nickel electrode to reduce oxygen migration ouside the stack and to prevent recombination on the adjoining negative electrodes. This paper outlines an approach to bipolar battery design, describes key issues related to the development of suitable electrodes, oxygen, and electrolyte management systems and presents a preliminary assessment of battery performance. Although some of these technical issues are similar to related items encountered in fuel cells and CPV modules, their resolution will require innovative design and new fabrication technologies.
