PURPOSE:To obtain a captioned cell whose preset performance can be obtained in a short time and whose characteristic deterioration hardly occurs with a variation per hour by forming an Li containing metal hydroxide layer on the surface of a porous sintering body and converting it to an oxide layer, then forming an oxydizing agent electrode. CONSTITUTION:A metal hydroxide layer such as nickel hydoxide that contains Li is formed on the surface of a porous sintering body made of conductive metal material such as Ni by the electrochemical method. Then the layer is electrolytically oxidized and is converted to an oxide layer such as nickel oxide that contains Li to obtain an oxidizing agent electrode. A unit cell is formed by inserting a fused carbonate electrolytic layer between this oxidizing agent electrode and a fuel electrode. Since the oxide layer of this unit cell excellently diffuses Li and has high electronic conductivity and high elasticity there hardly occurs exfoliation in thermal stress at temperature rise. As a result, a fused carbonate type fuel cell with ever-stable performance can be manufactured. |
