The present invention provides a composite oxygen electrode, comprising - a porous backbone structure comprising two separate but percolating phases, the first phase being an electronic conducting phase, the second phase being an oxide ion conducting phase; and - an electrocatalytic layer on the surface of said backbone structure, wherein said electrocatalytic layer comprises first and second nanoparticles, wherein the first and second particles are randomly distributed throughout said layer, wherein the first nanoparticles are electrocatalytic active nanoparticles, and wherein the second nanoparticles are formed from an ion conducting material. The present invention further comprises a method of producing the above composite electrode, compris- ing the steps of: - forming a porous backbone structure comprising two separate but percolating phases, the first phase being an electronic conducting phase, the second phase being an oxide ion conducting phase; and - applying an electrocatalytic layer on the surface of said backbone structure, wherein said electrocatalytic layer comprises first and second nanoparticles, wherein the first nanoparticles are electrocatalytic active nanoparticles, and wherein the second nanoparticles are formed from an ion conducting material.

La présente invention porte sur une électrode composite à oxygène, comprenant : une structure de base poreuse comprenant deux phases séparées mais percolantes, la première phase étant une phase conductrice d'électrons, la seconde phase étant une phase conductrice d'ions oxydes ; et une couche électrocatalytique sur la surface de ladite structure de base, ladite couche électrocatalytique comprenant des premières et secondes nanoparticules, les premières et secondes particules étant réparties au hasard dans toute ladite couche, les premières nanoparticules étant des nanoparticules électrocatalytiques actives et les secondes nanoparticules étant formées à partir d'une matière conductrice d'ions. La présente invention porte en outre sur un procédé de production de l'électrode composite ci-dessus, comprenant les étapes consistant à : former une structure de base poreuse comprenant deux phases séparées mais percolantes, la première phase étant une phase conductrice d'électrons, la seconde phase étant une phase conductrice d'ions oxydes ; et appliquer une couche électrocatalytique sur la surface de ladite structure de base, ladite couche électrocatalytique comprenant des premières et secondes nanoparticules, les premières nanoparticules étant des nanoparticules électrocatalytiques actives et les secondes nanoparticules étant formées à partir d'une matière conductrice d'ions.
