PURPOSE:To smooth the stacking of a fuel cell, by providing second rails on a separator plate at the mutually-opposite edges thereof opposite first rails so as to extend perpendicularly to the directions of gas passages, define gas passage sections and prevent the separator plate from warping due to a heat treatment. CONSTITUTION:Second rails 4 of stainless steel are provided on a separator plate 1 opposite first rails 3 and placed on an oxidizing gas passage. Other second rails 5 of stainless steel are placed on a fuel gas passage. The second rails 4, 5 are located at the mutually-opposite edges of the separator plate 1 and extend perpendicularly to the directions of the gas passages. The second rails 4, 5 have grooves 41, 51 for making gas passage sections. The first rails 2, 3 and the second rails 4, 5 are provided on both the sides of the separator plate 1 so that both the sides of the plate are almost equally affected by a heat treatment. The plate 1 is thus prevented from being deformed by the heat treatment. |
