A fuel cell separator includes a rectangular flat plate having two unitary upper sealing flanges respectively comprising opposite marginal edges of the plate folded upwardly and back on themselves and two lower sealing flanges respectively comprising the other two marginal edges of the plate folded downwardly and back on themselves. Each of the sealing flanges includes a flat wall spaced from the plate and substantially parallel thereto and two accordion-pleated side walls, one of which interconnects the flat wall with the plate and the other of which stops just short of the plate, these side walls affording resilient compressibility to the sealing flange in a directiongenerally normal to the plane of the plate. Four corner members close the ends of the sealing flanges. An additional resiliently compressible reinforcing member may be inserted in the passages formed by each of the sealing flanges with the plate.

A fuel cell separator comprising a substantially flat, planar, gas-impermeable plate, and a sealing flange unitary with said plate and consisting of a peripheral margin of said plate folded back upon itself, said sealing flange including a first portion spaced from said plate and a second portion resilently compressible in a direction generally normal to the plane of said plate for accommodating variation in the spacing between said first portion and said plate, said second portion of said sealing flange comprises an accordion pleated portion interconnecting said first portion and said plate.
