<P>PROBLEM TO BE SOLVED: To provide a fuel pole used for a power generation cell of solid electrolyte fuel cell which yields high power density with using a fuel, containing a lanthanum gallate-based electrolyte as a solid electrolyte at high utilization rate. <P>SOLUTION: The solid electrolyte fuel cell uses a lanthanum gallate, based oxide ionic conductor as an electrolyte and includes a power generation cell with a porous air electrode formed on one side of the solid electrolyte and a fuel electrode formed on the other side. The fuel electrode is made of a sintered body containing nickel and ceria doped in it. The nickel in this sintered body has a bone structure of a porous network. The doped ceria is burned and turned into large-diameter particles, whose average value is in the range of 0.2 to 0.6 μm, which are independent and stick to the surface of nickel having the porous bone structure, and small-diameter ceria whose average value is in the range of 0.01 to 0.09 μm, which are independent and stick to the surface between the larger particles. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
