Title: SYSTEM FOR HIGH-TEMPERATURE TIGHT COUPLING OF A STACK HAVING SOEC/SOFC-TYPE SOLID OXIDES
Abstract:
The main subject matter of the invention is a coupling system (30) for high-temperature tight coupling of a stack (20) having SOEC/SOFC-type solid oxides, characterised in that it includes: a threaded hollow connector (31), intended for being attached to a gas inlet/outlet pipe (12), including an opening for establishing fluid communication with the inlet/outlet pipe (12); a smooth hollow connector (33), intended for being attached to a gas inlet/outlet pipe (52) of the stack (20), including an opening for establishing fluid communication with the inlet/outlet pipe (52), the smooth connector (33) and the threaded connector (31) including openings for establishing fluid communication; a threaded nut (32), engaging with the threaded connector (31) to form a screw/nut system and sliding relative to the smooth connector (33), comprising a first threaded portion and a second smooth portion in sliding contact with the smooth connector (33).
