The cost of machining the grooves for the separator that separates the fuel and fuel occupies a large portion of the cost. The groove processing of the separator is to form a passage that does not obstruct the flow of the reaction gas, and at the same time to form a protrusion for pressing the electrode against the electrolyte tile and contacting it at 1-j. As shown in Fig. 5, the protrusion II is formed by grooving on the end mill. . Moreover, the above protrusion 1)
Since it is necessary to ensure the flatness of the top of the tile in order to make the electrode contact with the tile, the thickness of the separator is thick. Therefore, the present invention aims to reduce the loss of the separator by 1, and also to reduce the overall height when used as a fuel cell stack by reducing the size by 1. be.

れる。In the production of the separator of the present invention as described in 1.C (i. When press-molding into a corrugated shape with a smooth curve), the plate of the corrugated part is elongated due to tensile stress during press-forming. This elongation is caused by local cracks in the separator. In order to prevent this, it is necessary to make the groove almost uniform over the entire surface of the corrugate.For this reason, the groove shape must be formed with a smooth curve such as an arc or a straight line to generate mass flow during plastic working.Father, Corrugate In order to prevent cracks in the steel plate, it is necessary to suppress the elongation rate ε, which is determined from the groove pitch P, the full height] and the plate thickness T, to less than the tensile elongation of the steel plate. When the groove shape is formed using only circular arcs, the groove elongation rate ε is defined as follows.
