The performance and the long-term operating properties of solid oxide fuel cells (SOFCs) using BaCeO{sub 0.8}GdO{sub 0.2}O{sub 3{minus}{alpha}} (BCG) ceramics as the electrolyte have been investigated. A hydrogen-air fuel cell using BCG electrolyte with a thickness of 0.5 mm exhibited good performance at 800 C. Its short-circuit current was 0.9 A/cm{sup 2}, and there was hardly any degradation of BCG electrolyte in 1,600 h of operation. When a quasi-fuel gas containing 8% CO{sub 2}, which was expected by the reformation of the city gas (CH{sub 4}) at 800 C, was supplied to this cell, its short-circuit current was 0.63 A/cm{sup 2} and the cell worked stably under the discharge current density of 100 mA/cm{sup 2} for 2,500 h. Some sintered metals (Fe, Co, Ni) were examined as a anode material for this electrolyte. Ni is a promising anode material for BCG electrolyte from the point of view of performance and durability.
