A flow plate for a humidifier, and to such a humidifier having a plurality of flow plates and water exchange membranes are described. The flow plate has a flow field with a plurality of free-standing support elements, wherein the support elements extend, at least in sections, perpendicular to the flat surface plane of the flow plate. Gas to be humidified or gas giving off moisture flows on the flow field. In the humidifier, the flow plates are arranged in a stack, wherein a membrane composite having at least one water exchange membrane is arranged between each pair of adjacent flow plates in the stack. The support elements improve the performance of the humidifier and therefore the number of flow plates can be reduced, making a lower-weight and space-saving design possible.

Flow plate for a humidifier

The application relates to a water transfer compound, preferably for use for the humidification of process gases for fuel cells, comprising:&#x2014;a water-permeable and essentially gas-impermeable water transfer layer as well as&#x2014;at least one thermoplastic protection layer which is water- and gas-permeable at least in sections, where&#x2014;the water transfer layer and the thermoplastic protection layer overlap each other at least in sections and comprise a first and a second overlapping area, where&#x2014;the water transfer layer in the first overlapping area is accessible for humid gases through the thermoplastic protection layer and the water transfer compound is thermocompressed in the second overlapping area so that the water transfer layer in the second overlapping area is not accessible for humid gases through the compressed thermoplastic protection layer.

Method for the production of a water transfer compound

A heat exchanger has a heat exchanging element with a first terminal plate closing the heat exchanging element on one of its sides and with at least one opening provided with a socket for fluids for the heat exchanger element. At least a first gasket carrier plate has a first lateral face arranged adjacent to the first terminal plate and an opposite second lateral face. The first gasket carrier plate has at least one passage opening leading from the first to the second lateral face for taking up at least one socket of the first terminal plate. A first sealing element is provided between the first terminal plate and the first gasket carrier plate. A second sealing element is provided adjacent to the second lateral face. The at least one socket of the first terminal plate is bulged outwardly to adjoin to the second sealing element at least in sections.
