In a solid oxide fuel cell having an anode, a cathode, and a dense electrolyte disposed between the anode and the cathode, the cathode having a ceramic-ionic conducting phase of a plurality of ionic conducting particles and a metallic phase of a plurality of metallic particles. The metallic phase includes a metal alloy having an oxide-to-metal transition temperature in the range of about 600EC to about 800EC. With this cathode, solid oxide fuel cell operating temperatures as low as about 600EC may be possible.
La présente invention concerne une cathode, qui dans une pile à combustible à oxyde solide comportant une anode, une cathode et un électrolyte dense placé entre l'anode et la cathode, comporte une phase de conduction céramique-ionique d'une pluralité de particules à conduction ionique et une phase métallique d'une pluralité de particules métalliques. La phase métallique comprend un alliage métallique à température de transition oxyde-métal qui figure dans une plage d'environ 600EC à environ 800EC. Avec cette cathode, il est possible d'obtenir des températures de fonctionnement de la pile à combustible à oxyde solide aussi basses que 600EC.
