The invention relates to a process medium guiding apparatus for a recombination system having a recombination device for the catalytic recombination of hydrogen and oxygen created in accumulators to form water. According to the invention, a process medium guiding apparatus for a recombination system having a recombination device for the catalytic recombination of hydrogen and oxygen created in accumulators to form water is to be provided. The process medium guiding apparatus is designed such that the recombination system is limited towards the outside and comprises at least one guiding element. The guiding element is arranged above the recombination device, so that a process medium, more particular water, is guided from the process medium guiding apparatus to at least a partial region of an interior region of the recombination system.
