ABSTRACT:
A metal-hydrogen cell (e.g., silver-hydrogen or nickel-hydrogen) of heat pipe design wherein a central heat pipe serves as a thermal path, a positive plate conductor and terminal, and a mechanical support for the stack. The positive plates are electrically, mechanically and thermally connected to the heat pipe in the stack center. The negative plate terminals are at the outside edge of the stack. The pressure vessel may be of spherical configuration to provide a light weight design which has a two to one stress advantage in hoop stress over a cylinder with the same wall thickness and internal pressure.
