Abstract: An apparatus for receiving a cuboidal object, which has three side edges of different length, in a motor vehicle, having a receiving space, which has an insertion opening, the length of which corresponds at least to the length of the longest side edge of the object and whose width corresponds at least to the length of the shortest side edge of the object, but at least in sections is smaller than the length of the side edge of the object with the medium length, wherein the receiving space is of such a size that the object after being inserted through the insertion opening in the receiving space can be rotated through an angle of at least approximately 90° about its longitudinal axis and can be moved to a storage position in the receiving space.

Abstract: The system generally includes an electrochemical pump for pressurizing a cryogenic gas, a heat exchanger for cooling the gas to below its inversion temperature, a Joule-Thomson flow restrictor to cool the gas by adiabatic expansion, a load heat exchanger that is thermally coupled to an electronic component or surface that requires cryogenic cooling, and a low-pressure flow path back to the pump. One or more reservoirs can be provided in the high-pressure and low-pressure flow paths. The flow paths can be thermally coupled by one or more regenerative heat exchangers. The electrochemical pump can be adapted to transport either protons or hydronium ions. Protons are preferably transported using pump components that do not contain water in any chemical form. Either hydrogen or oxygen can serve as the cryogen.
