Abstract
An electrochemical cell has an alkaline electrolyte comprising a stack placed in a container and composed of at least one anode and at least one cathode containing nickel hydroxide. An oxygen recombination system has at least one recombination electrode which is at least partially hydrophobic and has two opposite faces of large surface area. A first face is joined to the anode. The cell is characterized in that the recombination electrode is associated with a rigid structure which forms, in contact with the second face of the electrode, a nonreducible volume space of small width so as to allow oxygen access throughout the duration of use of the cell.
