Sealed storage cell with an improved recombination device

An aqueous alkaline electrolyte Ni-MH sealed secondary storage cell including a bundle of electrodes placed in a container and made up of a plurality of negative and positive electrodes, a space separating the negative electrodes from the positive electrodes containing a separator, in which cell said separator is permeable to gases and a recombination device is placed between two adjacent negative electrodes and has a wetting angle of at least 45°, an average pore section of at least 103 μm2, and a thickness from 0.2 mm to 5 mm and wherein said recombination device is electrically non-conductive.
