LANTHANIDE CHROMITE-BASED SOFC ANODES

摘要

A SOFC, with a solid electrolyte layer and at least one anode layer constituting a stratified structure. The anode layer incorporates a twice substituted lanthanide chromite, substituted by Sr on A sites and by Ni or Cu on B sites. The stratified structure comprises a composite layer comprising a major amount of the substituted lanthanide chromite and a minor amount of the material of the electrolyte layer. A typical compound used as substituted lanthanide chromite is La1-xSrxCr1-yNiyO3 wherein 0.01 < x < 0.3 and 0.01 < y < 0.5. In particular La0.85Sr0.15Cr0.9Ni0.1O3 is suitable for making an anode of a SOFC. The lanthanide may be Praseodymium.
