Abstract

L'invention concerne une interconnexion destinée à une pile à combustible à oxyde solide comprenant une superstructure compliante dotée d'une première partie définissant une zone de contact de plaque de séparateur et une seconde partie définissant une zone de contact d'électrode, ladite superstructure étant poreuse. Dans un mode de réalisation, cette superstructure est définie par une pluralité de substructures compliantes prévues dans un premier sens et une pluralité de substructures compliantes prévues dans un second sens afin de définir une structure tissée.
