摘要：In order to prevent electrical short-circuiting between separators (20, 30) on both sides of a power generating body (10), and to provide sealing protrusions (41, 42) for the anode and the cathode and a sealing protrusion (44) for a cooling medium in an aggregated manner on a single separator (20), a fuel cell sealing structure is provided with a power generating body (10), and a first and a second separator (20, 30) disposed on both sides of the power generating body (10) in the direction of thickness, and is configured so that the first sealing protrusion (41) contacting the outer perimeter of the power generating body (10), the second sealing protrusion (42) contacting the second separator (30) and located to the outside of the first sealing protrusion (41) in the peripheral direction, and a short circuit prevention rib (43) protruding in line with the first and second sealing protrusions (41, 42) are integrally formed from an electrically insulating elastomeric material on one surface of the first separator (20) in the direction of thickness, and the third sealing protrusion (44) contacting the surface of the second separator (30) on the reverse side from the power generating body (10) is integrally formed from an electrically insulating elastomeric material on the other surface of the first separator (20) in the direction of thickness.
