  • Nickel oxide-hydrogen cell
    Patent number: 4117206
    Abstract: Nickel/hydrogen cells have a long cycle life and other attributes making them desirable for electric vehicle applications, but their cost is high. Cost reduction is obtained by the use of positive electrodes with high capacity per unit area, e.g. porous sintered nickel oxide electrodes, which contain absorbed therein major quantities of the electrolyte. The structure of positive and hydrophilic negative electrodes and of separators is specially adapted for this purpose.

  • Form retaining hydrogen-storing material
    Patent number: 4110425
    Abstract: A hydrogen-storing material of known type, e.g. Mg, Ti, V, Nb, and alloys such as La-, Ti- and Co- alloys, is made form retaining without significant loss of hydrogen absorption and desorption properties by binding with a plastic having sufficient adhesion or binding strength. The hydrogen-storing material in granular form is mixed with the plastic in powder, emulsion, solution or melt form and then molded into the desired shape.
