Recombination system having a recombination device

Recombination system having a recombination device for catalytically recombining hydrogen and oxygen arising in storage batteries to form water, wherein the recombination device comprises at least one catalyst material in at least one subregion above a center line of the recombination device in relation to a position of a retainer of the recombination system for the recombination device has a first partial amount of the catalyst material, wherein the first partial amount is greater than a second partial amount of the catalyst material, which second partial amount is located originating from the center line of the recombination device toward the retainer, wherein the retainer is arranged in a ceiling region of the recombination system, a bottom region of the recombination system is located opposite with respect to the ceiling region, and the bottom region comprises an opening region, into which one or more gases are flowable from below into an interior of the recombination system.
