Patent ID: 7678486

Claim:
A separator for a fuel cell, comprising an electrically conductive flat plate and two flat plate shaped electrically conductive channel plates superposed on each other with said electrically conductive flat plate interposed therebetween, wherein a plurality of manifolds for passing a reaction fluid to an adjacent fuel cell are formed in said electrically conductive flat plate; through-channels for permitting the flowing of the reaction fluid are formed in said two electrically conductive channel plates; any one of said two electrically conductive channel plates is disposed so as to overlap a portion of each of the through-channels with each of the plurality of the manifolds in said electrically conductive flat plate; and the other electrically conductive channel plate has a portion protruded outwardly from an outer periphery of said electrically conductive flat plate, the through-channels being formed from a region contacting with said electrically conductive flat plate to said protruded portion.
