Abstract:
1. A sealing structure for pinching a membrane-electrode assembly of a fuel cell, the sealing structure comprising: a first elastomeric gasket which is integrally provided in a first separator on one side in a thickness direction of the membrane-electrode assembly; and a second elastomeric gasket which is integrally provided in a second separator on an opposite side in the thickness direction of the membrane-electrode assembly relative to the first gasket, wherein said first gasket has a main lip including a top surface that directly contacts said membrane-electrode assembly when said sealing structure is pinching said membrane-electrode assembly, and the top surface is planar in a non-compressed state, wherein said second gasket has: wherein the top surface of said main lip has a narrower width than said flat seal surface, and wherein said sub lip has a narrower width than the top surface of said main lip.
