A device for transferring fluid between two separate structures includes a rigid pipe with a double shell extending along a longitudinal axis. The pipe includes an outer-shell housing (in the inner vacuum space thereof), at least one inner duct for fluid transfer, and at first and second ends thereof, includes respective first and second rigid connections of the outer shell to the first structure and second structures, respectively. The first and second ends of the outer shell are rigidly connected to the at least one inner duct. The pipe comprises a system to compensate for movements in the longitudinal direction.

Fluid transfer device and apparatus including such a device

The invention relates to a device for the transfer of water and heat between a first and a second air flow. The inventive device consists of a stack of at least two transfer sub-assemblies having a lamellar configuration, each sub-assembly comprising a two-layer transfer structure with hydrophilic porous materials (), which is disposed between a first structure for the distribution of the first air flow () and a second structure for the distribution of the second air flow ().

Device for the transfer of water and heat between two air flows and use thereof for the humidification of fuel cell inlet gas

The invention concerns an elastomer seal () arranged in a generally rectangular groove of a bipolar plate (), comprising in at least two opposite corners one first loop () urged to be attached on a corner pin () of the plate () and at least a second loop () designed to be urged to be attached, when the two plates are assembled enclosing between them an exchanging membrane, to a corner pin of the other polar plate. The seal further comprises studs () received in recesses of the plate and forms projecting lugs () for crimping the terminals of electronic components. The invention is applicable to the production of fuel cells.
