Patent

CA 2718954

The present invention provides an all ceramics solid oxide cell, comprising an anode layer, a cathode layer, and an electrolyte layer sandwiched between the anode layer and the cathode layer, wherein the electrolyte layer comprises doped zirco-nia and has a thickness of from 40 to 300 µm; wherein the anode layer and the cathode layer both comprise doped ceria or both comprise doped zirconia; and wherein the multilayer structure formed of the anode layer, the electrolyte layer and the cathode lay-er is a symmetrical structure. The present invention further provides a method of producing said solid oxide cell.

La présente invention concerne une pile à combustible à oxyde solide entièrement en céramique, comprenant un couche anode, une couche cathode et une couche électrolytique prise en sandwich entre la couche anode et la couche cathode. La couche électrolytique contient du zirconium dopé et présente une épaisseur de 40 à 300 µm; la couche anode et la couche cathode contiennent toutes deux du cérium dopé ou du zirconium dopé; et la structure multicouche formée de la couche anode, la couche électrolytique et la couche cathode est une structure symétrique. La présente invention concerne également un procédé de production de ladite pile à combustible à oxyde solide.
