NOVELTY - The hydrogen occlusion alloy electrode contains nickel powder and hydrogen occlusion alloy powder. The hydrogen occlusion alloy powder contains rare earth elements and a transition element which occludes and discharges hydrogen, as main components. The hydrogen occlusion alloy powder consists of two or more types of hydrogen occlusion alloy powders having different hydrogen equilibrium dissociation pressure.    USE - For nickel hydrogen storage battery (claimed) for use with e.g. electric vehicle or power tool.    ADVANTAGE - The nickel hydrogen storage battery using the hydrogen occlusion alloy electrode, has high discharge capability and charging-and-discharging cycle capability.    DETAILED DESCRIPTION - The hydrogen occlusion alloy electrode contains nickel powder and hydrogen occlusion alloy powder. The hydrogen occlusion alloy powder contains rare earth elements and a transition element which occludes and discharges hydrogen, as main components. The hydrogen occlusion alloy powder consists of two or more types of hydrogen occlusion alloy powders having different hydrogen equilibrium dissociation pressure.    The high equilibrium pressure hydrogen occlusion alloy powder with the highest hydrogen equilibrium dissociation pressure, has a hydrogen equilibrium dissociation pressure of 0.65 MPa or more, under the conditions of 60 degreesC and hydrogen storage capacity of 0.5 wt.%.    The low equilibrium pressure hydrogen occlusion alloy powder with the lowest hydrogen equilibrium dissociation pressure, has a hydrogen equilibrium dissociation pressure of 0.1 MPa or less, under the conditions of 60 degreesC and hydrogen storage capacity of 0.5 wt.%. The high and low equilibrium pressure hydrogen occlusion alloy powders have lanthanum as rare earth element, and contains one or more types of elements chosen from nickel, cobalt, manganese and aluminum.    An INDEPENDENT CLAIM is included for nickel hydrogen storage battery (1).
