| 摘要 |
A fuel cell (11) comprises a cell member (1) including a flat-plate separator (3), an air electrode (4), a solid electrolyte (5) and a fuel electrode (6), spacers (10) arranged along peripheries of the separators among the separators of the cell members stacked up, air supply paths (7) for supplying air to the air electrodes, air being sent to the air electrodes through grooves (2) of the flat-plate separators and air supply paths, air exhaust paths (8) for exhausting excessive air, fuel supply paths (14) for sending fuel to the fuel electrodes and fuel discharge (15) paths for discharging excessive fuel. The fuel cell has an oxidation-resistant coating layer on the surface of the separator on the side of the air electrode. The solid electrolyte is made by the use of one selected from the group of Laser Physical Vapor Deposition Method, Plasma Thermal Spraying Method, Electron Beam Vapor Deposition Method and Spattering Method. The air electrode comprises mixed powder of lanthanum mangan oxide doped with strontium oxide and yttria-stabilized zirconia. |
