<P>PROBLEM TO BE SOLVED: To provide an anode structure can obtaining high electrochemical activity under a wide range of temperatures by improving expansion of an electrode and low stability due to such expansion. <P>SOLUTION: A thermet anode structure can be obtained by a method including following steps, that is, by a step (a) in which slurry is prepared by dispersing powder of a conductive phase, and then by adding a binder to these dispersed powders, and at this time, the conductive phase contains an FeCrMx alloy in which Mx is selected from a group consisting of Ni, Ti, Nb, Ce, Mn, Mo, W, Co, La, Y, Al, and their mixtures, a step (b) in which a metallic support body is formed from the slurry of the conductive phase, a step (c) in which precursor solution of cerium oxide is prepared, and this solution contains a solvent and a surfactant, a step (d) in which the structure of the step (b) is impregnated with the precursor solution of the step (c), a step (e) in which the structure obtained in the step (d) is calcined, and then a step (f) in which the steps of (d) to (e) are carried out at least once. <P>COPYRIGHT: (C)2009,JPO&INPIT |
