Embodiment 1
[0093] FIG. 1 is a front view of an anode-side separator, and FIG. 2 is a rear view.
[0094] One anode-side separator 10 has a pair of fuel gas manifold holes 12 , a pair of oxidant gas manifold holes 13 , a pair of cooling water manifold holes 14 , a pair of spare manifold holes 15 and four bolt holes 11 .
[0095] The anode-side separator 10 has a gas flow passage 12b on the anode-facing side connected to the pair of fuel gas manifold holes 12 for supplying fuel gas to the anode and discharging fuel gas flow from the anode. The gas flow path 12b is constituted by a groove. The connection groove 12c connects the gas flow passage 12b and the fuel gas manifold hole 12 .
[0096] The partition plate 10 has a cooling water flow passage 14b connected to the pair of cooling water flow header holes 14 on its back side. The channel 14b is formed by two parallel grooves. Separator 10 also has O-ring grooves 12 a , 13 a and 15 a for receiving O-rings surrounding each of fuel gas ma...

[0153] (i) Manufacturing of separators
[0154] In Example 1, the anode-side separator shown in FIGS. 1 and 2 and the cathode-side separator 20 shown in FIGS. 3 and 4 were fabricated by processing an isotropic graphite plate. The thickness of the separator was 3 mm. The grooves constituting the gas and cooling water passages had a width of 2 mm and a depth of 3 mm.
[0155] (ii) Manufacture of seals
[0156] Such as Figures 5 to 8 As shown, the sealing composites 30 and 40 of Example 1 were fabricated with an adhesive layer.
[0157] A polymer film 4a with a thickness of 100 μm is placed in the mould. After the mold is clamped, at a temperature of 200°C and 150kgf / cm 2 The fluororubber is injection-molded under the molding pressure of 100 to form a predetermined seal 36 on the polymer film 4a. Also, a sealing member 46 was molded on the polymer film 4b having a thickness of 100 µm. Then, it was subjected to a secondary cross-linking treatment for 10 hours at a temperat...
