La(0.75)Sr(0.25)Cr(0.5)Mn(0.5)O(3-delta) (LSCrM)-impregnated anodes have been fabricated by infiltrating 70% porous yttria-stabilized zirconia (YSZ) matrixes with an LSCrM solution. In these anodes, LSCrM is a primary electronic conducive phase while the well-sintered YSZ provides an ionic-conducting pathway throughout the electrode. The maximum power densities of a single cell with YSZ+35wt.% LSCrM composite anode reach 567 and 561 mW cm(-2) at 850 degrees C in dry H(2) and CH(4), respectively. Further, Ag and Ni are added via nitrate impregnating method for improving electronic conductivity and catalytic activity. With the addition of 6wt.%Ni and 2wt.% Ag to the YSZ+32wt.% LSCrM composite anode, the maximum power densities at 850 degrees C increase to 1302 mWcm(-2) in dry H(2) and 769mWcm(-2) in dry CH(4). No carbon deposition is detected in the tested anodes, even with the presence of Ni. (C) 2009 Elsevier B.V. All rights reserved.
