Abstract: A method for determining a sealing tightness of a fuel cell stack includes providing of fuel into a cathode space, sealed off gas-tight against further components of a cathode subsystem, formed at least partly by the fuel cell stack, and detecting of a value which is indicative of a pressure change in the cathode space, where a cathode test pressure in the cathode space is higher than a pressure outside the fuel cell stack.

Abstract: A process for safeguarding a product during transportation includes forming a package by surrounding a product with packaging material and accommodating the package in an external packaging that includes a carrier element and a bag element. The carrier element includes an upper side including a border and a lower side opposite the upper side, wherein the lower side includes a base. Further, the bag element includes a base and a bag opening with a border opposite the base of the bag element. The package is accommodated in the external packaging by loading the package onto the carrier element such that the package is carried by the carrier element and loading the carrier element via the bag opening into the bag element such that the bag element surrounds the carrier element and the bag element extends on the upper side of the carrier element beyond the border of the carrier element.

Abstract: A method is provided for purging a fuel cell. The method is characterized by suctioning the purge gas through the fuel cell by use of low pressure.

Abstract: An exhaust system is provided for a device having at least one fuel cell. The exhaust system includes at least one exhaust duct for transporting anode-side and/or cathode-side exhaust gas of the fuel cell, at least one air inlet for supplying air, at least one air feeding device for feeding in the supplied air, at least one heat exchanger for heating up the supplied air, a mixing region for mixing exhaust gas of the fuel cell transported by way of the exhaust duct with the supplied air and forming a mixed exhaust gas, and a mixed exhaust gas outlet for carrying the mixed exhaust gas away from the exhaust system.

Abstract: A fuel cell system, in particular for a motor vehicle, has a fuel cell stack arranged in a housing and a measure for ventilating this housing by coupling the ventilation stream to another gas stream. The ventilation stream is fed to an air stream which is conducted through a radiator of the fuel cell system. The radiator is an ambient air heat exchanger. If the ventilation stream is fed in upstream of the radiator, a venting opening in the housing can be placed in such a way that the ventilation stream is entrained to the radiator by the inflow air stream. Alternatively, the ventilation stream can be fed to an exhaust gas stream of the fuel cell stack and the latter can be fed to the outflow stream of the radiator. A sensor for determining the hydrogen content in a gas stream downstream of the point where the ventilation stream is fed may be provided.

Abstract: A method for packaging articles to be transported is provided comprising a) preparing at least one pallet comprising a base plate, which base plate forms an even plate-shaped element; b) placing the articles to be transported onto the base plate; c) providing a transport box that's open toward the base plate in an inverted orientation over the articles, wherein the transport box is placed on the base plate so that the transport box and base plate together form an interior of the transport packaging unit, wherein the transport box comprises an opening that's closable by folding flaps on a side opposite the base plate, wherein the transport box closes off flush with the pallet; and d) fixing the transport box on the base plate with at least one packing strip, wherein the transport box is pressed onto the base plate by said at least one packing strip.

Abstract: Disclosed is a transport packaging unit for packaging articles to be transported, in particular hazardous materials. The transport packaging unit comprises the following: a pallet with a base plate, wherein the articles to be transported are receivable on the base plate; a transport box which is open toward the base plate, wherein the transport box rests on the base plate and together with the base plate forms an interior of the transport packaging unit which receives the articles to be transported, wherein the transport box is fixed on the base plate by means of at least one fastening element, preferably by means of at least one packing strip.

Abstract: A process for safeguarding a product during transportation comprises forming a package by surrounding a product with packaging material and accommodating the package in an external packaging that comprises a carrier element and a bag element. The carrier element includes an upper side including a border and a lower side opposite the upper side, wherein the lower side comprises a base. Further, the bag element comprises a base and a bag opening with a border opposite the base of the bag element. The package is accommodated in the external packaging by loading the package onto the carrier element such that the package is carried by the carrier element and loading the carrier element via the bag opening into the bag element such that the bag element surrounds the carrier element and the bag element extends on the upper side of the carrier element beyond the border of the carrier element.

Abstract: An external packaging for safeguarding at least one package during transportation is provided. The external packaging includes at least one carrier element with an upper side and a lower side, wherein the carrier element includes at least one base part directed toward the lower side and at least one border directed toward the upper side, and wherein the carrier element is at least partially open toward the upper side and is configured to carry the package. The external packaging furthermore has at least one bag element which is configured to surround the package carried by the carrier element. The bag element is arranged relative to the carrier element in such a manner that the bag element, at least in a maximum filling state, extends on the upper side of the carrier element beyond the border of the carrier element.

Abstract: A method and an apparatus check a computer system for blocked or incorrectly allocated memory areas, which can arise as a result of termination of a process which accesses the memory in addition to other processes. This is checked by recording a first state vector before the start of the process and a second state vector describing the state of the memory after termination. The two state vectors are then compared for a match.
