<P>PROBLEM TO BE SOLVED: To provide a separator for fuel cell capable of suppressing position shifting between each plates in a separator of three-layer structure. <P>SOLUTION: The separator constituting a fuel cell comprises an intermediate plate 1 having a penetrated part, a first plate 2 contacting a first face of the intermediate plate, a second plate 3 contacting the second face of the intermediate plate, a first protrusion 27 which is installed on the intermediate plate side of the first plate and has a crown portion and a side portion, and a second protrusion 37 which is installed on the intermediate plate side of the second plate and has a crown portion and a side portion. The first protrusion is arranged at a position overlapping with the penetrated part of the intermediate plate viewed from lamination direction and the second protrusion is arranged at a position which overlaps with the penetrated part of the intermediate plate viewed from lamination direction and in which at least part of the side portion of the second protrusion contacts at least part of the side portion of the first protrusion. <P>COPYRIGHT: (C)2007,JPO&INPIT |
