Abstract

L'invention concerne une cathode bicouche destinée à une pile à combustible haute température. Cette cathode bicouche comporte une cathode proprement dite ainsi qu'une couche fonctionnelle de cathode appliquée sur un électrolyte. Cette cathode se caractérise en ce que la couche fonctionnelle de cathode contient de l'argent, le reste étant constitué de lanthane-strontium-manganite (LaSrMn03: LSM), la teneur en argent étant d'au moins 60 % en volume. De façon particulièrement avantageuse, la cathode proprement dite contient également de l'argent, par exemple à une concentration de 30 % en volume. Le procédé mis en oeuvre pour la production de la cathode bicouche selon l'invention est soit un procédé de sérigraphie, soit un procédé de pulvérisation humide.
