PURPOSE:To enhance the bonding force between the surface of an electrolyte and electrodes and exhibit the performance as a fuel battery for a long time by forming a positive electrode and a negative electrode after forming uneven parts on the electrolyte surface by means of plasma spraying. CONSTITUTION:In a fuel cell, both the surfaces of a solid electrolytic plate 1 consisting of a sintered body of zirconia stabilized or partly stabilized by yttrium oxide, calcium oxide or magnesium oxide, or the like are covered with a positive electrode 2 and a negative electrode 3. The positive electrode and negative electrodes are provided with a positive electrode collector 4 and a negative electrode collector 5, for taking out a generated electricity, having gas supply channels to both the electrodes. These unit fuel cells are laminated through an interconnector 6 consisting of a heat resisting alloy or LaCrO3. An uneven part is formed on at least one surface of the solid electrolytic plate 1 to improve the adhesion of the electrodes. |
