Title:
FUEL CELL AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP3712592
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell for allowing the improvement of sealability between an electrode membrane structure and a separator and its manufacturing method.
SOLUTION: A cell of the fuel cell composed of a solid polymer electrolyte membrane 18 and at least an anode electrode 22 and a cathode electrode 20 at each opposed end thereof is configured to be pinched between by the first separator 14 and the second separator 16. Around the solid polymer electrolyte membrane 18 is provided a projection 18a protruding from the anode electrode 22 periphery and the cathode electrode 20 periphery. Each groove portion 28 is provided in a position corresponding to the projection 18a of the solid polymeric electrolyte membrane 18, which is a periphery in the surface of respective separators 14, 16. The fuel cell is pinched between by the separators 14, 16 with a fluid sealant S applied to the groove portion 28 in a close contact with the projection 18a of the solid polymer electrolyte membrane 18.
