N2 - Generally, cermet anode is produced by mixing nickel oxide with stabilized zirconia. Improvement of the conventional anode is necessary in the viewpoints of electrochemical performance and its productivity. In this study, two approaches were tested in order to enhance the anode performance. First, wet blended Ni-Zr composite hydroxide was applied as a precursor to obtain homogeneous Ni-stabilized zirconia cermet. In the next phase, doping of Mg, Mn and Co to the nickel precursor is performed by co-precipitation method aiming at positive effects of these elements, and electrochemical properties of these anodes are evaluated and compared to those of conventional anode.
