Abstract:
A fuel cell stack seal structure of a fuel cell stack, the fuel cell stack including a plurality of fuel cell single cells that are stacked, each of the fuel cell single cells including a membrane electrode assembly and a pair of separators holding the membrane electrode assembly between the pair of separators, includes inner peripheral sealing members and an outer peripheral sealing member at peripheral edges of a pair of separators, in which the inner peripheral sealing members close a gap between inner peripheral ribs that protrude at least towards a mutually facing sides of the pair of separators, and the outer peripheral sealing member that closes a gap between outer peripheral ribs that protrude at least towards the mutually facing sides of the pair of separators. The inner peripheral sealing members and the outer peripheral sealing member form a first closed space between the inner peripheral sealing members and the outer peripheral sealing member. The outer peripheral sealing member has a notch that communicates the first closed space with the outside.

Claim (Index 38):
The method for producing the fuel cell stack seal structure according to  claim 37 , wherein the outer peripheral rib comprises a protruded face and a distance between the protruded faces of the pair of separators is uniform, and the outer peripheral rib forms a narrow path at which a distance between the pair of separators is shorter than a distance between the outer peripheral ends of the pair of separators,\n an inner peripheral end of the outer peripheral sealing member is disposed in the narrow path, the outer peripheral sealing member comprises inner-outer peripheral sealing members and an outer-outer peripheral sealing member, the inner-outer peripheral sealing member is disposed integrally in the narrow path and at an outer side of the narrow path, the outer-outer peripheral sealing member is disposed at an outer side of the inner-outer peripheral sealing members, and\n the outer peripheral sealing member comprises a notch forming member at the notch, and \n wherein Step (1) comprises setting an unapplied area for forming the notch in such a position as to form the first closed space and a part of the notch, and further applying a material of the inner-outer peripheral sealing members as a part of the outer peripheral sealing member to at least one of the pair of separators in an area from the narrow path of the pair of separators to an outer side of the narrow path, \n Step (2) comprises disposing the notch forming member at the unapplied area in a side face of the stack structure, and \n Step (3) comprises injecting a material of the outer-outer peripheral sealing members as a part of the outer peripheral sealing member so as to form the outer-outer peripheral sealing member and a remaining part of the notch at an outer side of the inter-outer peripheral sealing members.
