Layered structures and associated fabrication methods that serve as the foundation for preparing high-operating-temperature electrochemical cells have a porous ceramic layer and a porous metal support or current collector layer bonded by mechanical interlocking which is provided by interpenetration of the layers and/or roughness of the metal surface. The porous layers can be infiltrated with catalytic material to produce a functioning electrochemical electrode.

Cette invention se rapporte à des structures en couches et à des procédés de fabrication associés qui servent de base pour préparer des cellules électrochimiques à température de fonctionnement élevée. Ces structures comportent une couche céramique poreuse et une couche métallique poreuse de support ou de collecte de courant liées par un interverrouillage mécanique qui est créé par l'interpénétration des couches et/ou la rugosité de la surface métallique. Les couches poreuses peuvent être imprégnées d'un matériau catalytique afin de produire une électrode électrochimique fonctionnelle.
