PROBLEM TO BE SOLVED: To provide a manufacture of an NiO and/or Ni/YSZ composite powder used in a solid electrolyte fuel cell as a fuel electrode and contributable to improvement of a power generating characteristic and particularly durability of the cell. SOLUTION: A coagulation of Ni under an SOFC operation condition is suppressed by calcining an NiO/YSZ composite powder with a desired ratio of nickel elements, zirconium elements, and yttrium elements in an air atmosphere or a reducing atmosphere for obtaining a green compact, and furthermore performing heat treatment to the green compact in an air atmosphere or a reducing atmosphere for evenly dispersing NiO particles or Ni and YSZ particles and also improving adhesion. |
