Abstract
A cermet anode structure obtainable by a process comprising the steps of: (a) providing a slurry by dispersing a powder of an electronically conductive phase and by adding a binder to the dispersion, in which said electronically conductive phase comprises a FeCrMx alloy, wherein Mx is selected from the group consisting of Ni, Ti, Nb, Ce, Mn, Mo, W, Co, La, Y, Al, and mixtures thereof, (b) forming a metallic support of said slurry of the electronically conductive phase, (c) providing a precursor solution of ceria, said solution containing a solvent and a surfactant, (d) impregnating the structure of step (b) with the precursor solution of step (c), (e) subjecting the resulting structure of step (d) to calcination, and (f) conducting steps (d)-(e) at least once.
