<P>PROBLEM TO BE SOLVED: To provide a fuel electrode material which can be manufactured by mass production at a low cost by using a simple manufacturing technique and can stably maintain high performance for a long time, in a fuel electrode material for a solid electrolyte fuel cell having an optimum microstructure. <P>SOLUTION: The fuel electrode material is for a nickel-zirconia system solid electrolyte fuel cell, composed of a mixture of a group of zirconia coarse particles having relatively large particle sizes, a group of zirconia fine particles having relatively small particle sizes, and a group of nickel or nickel oxide particles. Particle sizes of each group of particles satisfy a relation: zirconia coarse particle > nickel or nickel oxide particle > zirconia fine particle. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
