Disclosed is a method of producing a sealed metal oxide-hydrogen storage cell, comprising the step of housing in a container a cathode containing a metal oxide as an active material, an anode containing a hydrogen storage alloy as the main component, a separator for separating the cathode and the anode, a pre-charging member, and an electrolyte solution consisting of an alkaline aqueous solution. The pre-charging member is electrically combined with the anode and consists of a metal having a less noble potential than the hydrogen electrode potential within the alkaline solution. A material containing said metal as the main component may also be used as the pre-charging member. The storage cell has a desired anode-cathode capacity balance and exhibits a long life.
