Abstract: An electrochemical system includes an electrochemical device having a stack of n solid oxide electrochemical cells, n being an integer greater than or equal to 1. The electrochemical system also includes at least n?1 interconnection plates which are interposed between the electrochemical cells, and means for supplying gas to the electrochemical cells and means for collecting gas produced by the electrochemical cells. The electrochemical system further includes means for electrically connecting the system to the outside. The electrochemical device also includes heating means integrated into the stack, said heating means comprising electrical conductors housed in the clamping plates.

Abstract: An interconnector for an electrochemical module includes a stack of electrochemical cells and interconnectors, each cell being disposed between two interconnectors and in electrical and mechanical contact with the interconnectors, and electrical insulating elements between two interconnectors and surrounding a cell. The interconnector includes at least one intermediate plate received between two end plates defining gas supply and gas collection chambers therebetween. The intermediate plate includes a central region delimited externally by a lateral region having n lateral branch regions, n being at least equal to 1, each lateral extension being configured to be movable towards and to come into contact with a lateral extension of an intermediate plate of a directly adjacent interconnector in the stack, so as to provide electrical conduction between the two interconnectors, the intermediate plate not being covered by at least one of the two end plates at a lateral branch region.

Abstract: A device for converting a liquid into vapor includes an enclosure, a heating surface with a downward slope arranged in the enclosure, and a liquid inlet port connected to an upper portion of the heating surface so that a liquid introduced from the liquid inlet port flows on the heating surface. The device also includes a vapor outlet port formed through a wall of the enclosure. The heating surface includes a heat transfer pipe configured to allow the flowing of a heat transfer fluid to heat the heating surface, and a corner piece including a U-shaped cross-section with a semi-circular portion arranged around the heat transfer pipe and an upper portion forming an opening on the enclosure.

Abstract: A liquid-to-vapor conversion device includes a chamber having an opening connected to a liquid intake, a pressure relief opening, and a vapor outlet. The device also includes a flow controller arranged at the level of the liquid intake, and a burst disk installed at the level of the pressure relief opening. Further, the device includes pressure-limiting means arranged at the level of the liquid intake. The pressure-limiting means is configured to decrease the flow rate in the liquid intake when the pressure in the liquid intake exceeds a threshold value smaller than a bursting pressure of the burst disk.

Abstract: An electrochemical system includes an electrochemical device having a stack of elementary electrochemical cells each including an electrolyte interposed between a cathode and an anode; ducts for supplying the anodes and the cathodes with gas and for collecting the gases generated by the latter; an enclosure having the electrochemical device housed therein and including at least one inlet duct and one outlet duct to circulate an air flow in the enclosure; and a circuit for analyzing the air in the enclosure. The circuit includes a sensor capable of measuring an oxygen content present in the outlet duct of the enclosure; and an analysis unit capable of diagnosing a leak of the device when the measured oxygen content differs from a predetermined oxygen content in the inlet duct of the enclosure.
