<P>PROBLEM TO BE SOLVED: To provide a separator for a fuel cell which has extremely high corrosion resistance, and superior mechanical strength, in which variations in dimension due to shrinkage after forming and/or after sintering are reduced to the minimum, and which, by suppressing the final manufacturing process to the minimum, becomes inexpensive, highly productive, and highly suitable for manufacturing the fuel cells of solid polymer type or the like, and also to provide its manufacturing method. <P>SOLUTION: The separator A for the fuel cell is composed by sintering treatment after grooves are formed by forming molds on both faces of front and rear faces. The grooves of an area ratio 90% or more out of groove part 10 in the groove pattern 20 of the rear side faces exist in plane symmetrical positions in relation to the front and the rear side faces. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
