SOLUTION: A cell 4 includes a pair of separators 5A, 5B consisting of thin plates of titanium, a rubber 6 for insulation provided therebetween, and an electrolyte, an air electrode and a fuel electrode (not shown) sandwiched on the inside of both separators 5A, 5B. On the outer surface 5Aa of one separator 5A, an endless seal member 7 is provided along the contour of separator 5A. The seal member 7 made of rubber is applied to the outer surface 5Aa of one separator 5A in about 10 seconds by screen printing. An endless full bead 5Ba is formed on the other separator 5B so as to bulge toward the seal member 7 of an adjacent cell 4. When a large number of cells 4 are fastened, in laminated state, by means of fastening bolts and nuts, the full bead 5Ba of one adjacent cell 4 comes into close contact strongly with the seal member 7 of one adjacent cell 4 (refer to Fig. 2(b)).EFFECT: A seal structure excellent in productivity and sealability, compared with conventional products, can be provided.SELECTED DRAWING: Figure 2 |
