PROBLEM TO BE SOLVED: To provide a fuel battery unit cell with an interconnector excellent in reliability, and capable of suppressing reduction of weldability.SOLUTION: A fuel battery unit cell 2 with an interconnector is constituted by laminating a tabular unit cell 2, a fuel electrode frame 13, and a tabular interconnector 14. The fuel electrode frame 13 and interconnector 14 are joined via weld zones 70, 71. In a region R1 of the surface 41 of the interconnector 14 facing the fuel electrode frame 13, excepting at least the weld zones 70, 71, a first coating layer 42 is formed. A second coating layer 45 is formed entirely on the other surface 44, i.e., the back side of the surface 41 of the interconnector 14.SELECTED DRAWING: Figure 6 |
