TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: In the fuel cell module: the second region is located adjacent to a side of the unit cell through which a fuel is injected; the third region is located adjacent to a side of the unit cell through which the fuel is discharged; and the first region is located between the second region and the third region. The second ionic conductivity and the third ionic conductivity are higher than the first ionic conductivity, when the first, second and third regions have a same temperature. The second ionic conductivity is equal to the third ionic conductivity. The second region has the same area as that of the third region or the first region, where an area ratio of the second region to the first region is 3:5-4:3. The first, second and third regions have different areas respectively, where the area of the third and first regions are larger than that of the second region, or the area of the second region is larger than that of the first region. EXAMPLE - Powder of rare-earth oxide (including yttrium oxide) was mixed with powder of nickel and/or nickel oxide to obtain a mixed powder. Then the mixed powder was mixed with organic binder and a solvent to obtain a mixture. The resultant mixture was then extruded to obtain a support body. The resultant extruded support body was then dried and sintered at 1250 degrees C. Then an oxide powder containing powder of nickel and/or nickel oxide and rare-earth elements (yttrium oxide and zirconium dioxide) was mixed with an organic binder and a solvent to form slurry. Then an anode layer was coated on the support body using the slurry. Then an electrolyte layer was coated on the support body coated with the anode layer using the slurry. The resultant support body coated with the electrolyte layer was then simultaneously sintered under the oxygen containing mood at 1300-1600 degrees C. Then a powder of transition metal (lanthanum strontium manganite oxide) was mixed with a solvent to obtain a paste. Then the obtained paste was coated to the first region, the second region and the third region. Then the first region was masked, and the paste coated to the second region and the third region was annealed at 1000-1300 degrees C to obtain the fuel cell.
