Solid oxide fuel cells (SOFCs) consist of three layers; a cathode, an electrolyte and an anode. The anode consists of three phases; yittria-stabilized zirconia (YSZ), Ni and pore. In the anode, O^<2->, electrons, and gases pass through in YSZ, Ni, and pore, respectively. In a conventional anode, the three phases are uniformly distributed and the structure is not always appropriate in the view point of the transfer paths of O^<2->, electrons and, gases. In our previous research, the efficiency of power generation was improved by applying magnetic field in anode during the fabrication process. The magnetic field improved the connection of Ni and makes Ni array in anode. In this study, a difference in behavior of different-shaped Ni particles was observed by scanning electron microscopy. An orbicular Ni particle moved better than a rough Ni particle when a magnetic field is applied. The thickness of Ni array became thicker when a stronger magnetic field is applied.
