Superplastic gasket, preferably for a system of electrochemical cells

摘要

The joint (10) has contact portions (16) spaced along spacing direction to sealingly contact elements i.e. electrolyte (6) and anodic interconnector (2'), which are made of metal or ceramic. The portions are made of an alloy having superplasticity properties in preset solicitation conditions among preset temperature conditions, and carried by a support (22) placed between the portions. The support is made of another metal alloy presenting, in the temperature conditions, a mechanical compression resistance in the direction, where the resistance is higher than that the alloy of the portions. Independent claims are also included for the following: (1) an electrochemical cell system comprising an anode (2) a method for placing a sealing joint.
