  "textContent": "A subject for the invention is to provide a sealed nickel-hydrogen cell which has an increased capacity attained by reducing the initial generation of a negative-electrode discharge reserve and which has excellent discharge performance, e.g., high-rate discharge performance, and has high productivity. The invention provides a process for producing a sealed nickel-hydrogen cell which has positive-electrode active material particles constituted of a core layer comprising, as the main component, nickel compounds including nickel oxyhydroxide and a surface layer covering the core layer and comprising a cobalt compound and further has hydrogen-absorbing alloy particles, the process comprising the step of oxidizing the core layer and the cobalt contained in the surface layer of the positive-electrode active material before cell assembling, the step of conducting a charge-discharge operation at least once after cell assembling, and the step of conducting aging after the charge-discharge operation.",
