NOVELTY - The housing has a temperature control device (16) that is provided for cooling and warming the galvanic element (14) in the housing interior portion (12). The temperature control device is flowed through by a keeping at a moderate temperature fluid. A pressure equalization device (22) comprises one inlet valve (26), an exhaust opening (36) and an aperture (32) into the housing interior with a selectively permeable membrane (44). The pressure equalization device is in thermal contact with the temperature control device.    USE - Housing for galvanic element such as battery cell e.g. lithium iron cell, lithium polymer cell and lithium metal cell used in motor car (claimed). Can also be used in electrical motor cars (EV), hybrid electric vehicles (HEV), Plug in hybrid vehicles (PHEV) and fuel cell vehicles.    ADVANTAGE - The volumetric flow is intense reduced, as the pressure equalization device is in thermal contact with temperature control device. The inlet valve of the pressure equalization device is easily opened by control or regulating device. The air flowing into the pressure equalization device is cooled so as to dry the air under water condensation, so that a temperature control device is exploited favorably. The incoming air at the components does not continue to cool down and obviates a water condensation at components in the housing interior. The steered or regular discharging of the condensate results in particular favorably over an exhaust valve of the pressure equalization device, so that the housing takes place in a motor car at inaccessible locations. The dehumidifying of air runs to a large extent, so that corresponding housing with pressure equalization devices is accommodated even at difficulty accessible regions.
