Chamber for temperature-controlled storage of goods, in particular foodstuffs

The room module has an accessible box-shaped housing (1) insulated on all sides with an integral cooling unit. The interior of the housing is vertically or horizontally divided into a storage space and a space for an operating medium, whereby the storage space has an arrangement for temperature control. A fuel cell connected to an operating medium source is arranged in the operating medium space and electrically interacts with the cooling unit also in this space.
