Abstract

A cryogenic pressure container for a motor vehicle has an inner container and an outer container. An evacuated space is arranged between the inner container and the outer container at least in some regions. The inner container has a synthetic material layer. A barrier layer is arranged at least in some regions between the synthetic material layer and the evacuated space. The barrier layer is designed and arranged so as to at least reduce the transfer of constituents leaking out of the synthetic material layer into the evacuated space, wherein a gap is formed at least in some regions between the barrier layer and the synthetic material layer.
