Abstract: A device and method for producing complex multipart collections (K1) of printed products includes at least two partial collections (T1, T2, T3) of precursors. The device comprises a collating device (6) having a conveyor track (41) on which a plurality of receptacle units (50) circulate in a closed circuit for receiving collated precursors, and on which a plurality of feeder apparatuses (101-112) are disposed in at least one collating region (11, 12), from which precursors are dispensed into the receptacle units (50) moving past on the conveyor track. A transfer apparatus (30) is disposed in at least one location of the conveyor track (42), transferring collated first partial collections (T1) from the receptacle units (50) for further processing, and a collator (31, 32) is disposed in at least one further location of the conveyor track (41, 43), collating further collated partial collections (T3, T4) from the receptacle units (50) into collections (K1).

Abstract: A support device for the support of conveyed objects includes a roller body with a series of rollers, which run along a path and support the conveyed objects in a support region. The rollers roll in the support region on a support surface. Thereby, the following steps are carried out: relieving the rollers on entering into a part region of the support region; aligning the relieved rollers; renewed loading of the rollers on leaving the part region of the support device. For this, at least one recess of the support surface is present in the support region, wherein a roller which is located in the region of the recess, may be moved into the recess.

Abstract: A support device for conveying heavy loads includes a support body and a roller body which revolves around the support body, wherein the roller body includes a series of support rollers and distancing rollers, the distancing rollers have a smaller diameter than the support rollers, and the distancing rollers in each case space consecutive support rollers from one another, and the support device is provided for supporting a load which moves along a support region, and the roller body at least in the support region is covered in its whole width by a belt, and thus in the support region, the support rollers roll on the support body and on the belt.

Abstract: A fuel cell stack is disclosed having a number of stacked fuel cells, each having in series an anode-facing end plate, an anode, an ion-exchanging layer, a cathode and a cathode-facing end plate. The stack includes at least one conductive and flexible intermediate layer between elements of the stack. The intermediate layer is deformable implemented in terms of its thickness. The intermediate layer abuts and interacts, in a fluid-tight manner, with the end plates. The intermediate layer is further disposed between at least one of the anode-facing end plate and the cathode-facing end plate of adjacent fuel cells, an end plate of a stack and a cooling plate attached to said end plate and an end plate of the stack and a cathode-facing end plate.

Abstract: A fuel cell has an electrochemical process area having a cathode area, an anode area and an ion-exchanging membrane that separates these areas. The cathode area has a gas passage way having a gas inlet, a gas channel and a gas outlet, wherein the gas passage way is for an oxygen-containing gas to flow from the gas inlet through the gas channel to the gas outlet. The fuel cell includes further a humidity transfer area having a dehumidifying zone, a humidifying zone and a humidity transfer membrane that separates these zones. An exhaust channel connects the gas outlet to the dehumidifying zone, and an inlet channel connects the gas inlet to the humidifying zone. Humidity is extracted from the oxygen-containing gas in the dehumidifying zone, and added to the oxygen-containing gas in the humidifying zone via the humidity transfer membrane.

Abstract: So that the electrolyte membrane of a fuel cell in the inlet area of the fuels does not dry out, a humidity circuit is provided on the cathode side and/or anode side, by means of which e.g. a fluid entering the cell on the cathode side is first humidified, so that the membrane itself no longer discharges any humidity to the fluid, but can absorb it if required and thus does not dry out.

Abstract: The present invention is directed to an intermediate layer between end plates of a fuel cell enables individual fuel cells to be removed form the stack in a simple manner, thus reducing production costs.
