Abstract[English]
A porous electrode layer for a solid oxide electrolysis cell (SOEC) is provided, said electrode layer being a composite comprising dispersed nickel particles and stabilised zirconia particles, said composite further comprising at least one transition metal (TM) from Groups 3 – 12 as dopant. The transition metal (TM) is present in said porous electrode layer in an amount of between 0.0001:1 – 0.25:1, or 0.0001:1 – 0.1:1, expressed as a molar ratio (TM:Ni) of the transition metal (TM) to the nickel (Ni). A powder mixture, suitable for producing the porous electrode layer, and an SOEC comprising said layer are also provided.[French]
L'invention concerne une couche d'électrode poreuse pour une pile d'électrolyse à oxyde solide (SOEC), ladite couche d'électrode étant un composite comprenant des particules de nickel dispersées et des particules de zircone stabilisées, ledit composite comprenant en outre au moins un métal de transition (TM) des groupes 3-12 en tant que dopant. Le métal de transition (TM) est présent dans ladite couche d'électrode poreuse en une quantité comprise entre 0,0001/1 à 0,25/1, ou 0,0001/1 à 0,1/1, exprimé en rapport molaire (TM/Ni) du métal de transition (TM) au nickel (Ni). L'invention concerne également un mélange pulvérulent, approprié pour produire la couche d'électrode poreuse, et une SOEC comprenant ladite couche.
