<p>A nickel-hydrogen battery (110) or cell (100) having one or more pressure vessels (70) containing hydrogen gas and a plurality of cell-modules (10) therein. Each cell-module (10) includes a configuration of cooperatively associated gas and electrolyte management and component alignment features. A cell-module (10) having electrolyte includes a negative electrode (12), a positive electrode (16) adapted to facilitate oxygen diffusion, a separator (14) disposed between the positive and negative electrodes for separating them and holding electrolyte for ionic conductivity, an absorber (18) engaging the surface of the positive electrode facing away from the separator for providing electrolyte to the positive electrode, and a pair of surface-channelled diffusion screens (20) for enclosing the positive and negative electrodes, absorber, and separator, and for maintaining proper alignment of these components. The screens (20), formed in the shape of a pocket (22) by intermittently sealing the edges together along as many as three sides, permit hydrogen gas to diffuse therethrough to the negative electrodes, and prevent the edges of the separator from swelling. Electrolyte contained in the cell-module is absorbed by the electrodes, the separator and the absorber.</p> |
