Means for forming a seal between a fuel cell stack and manifolds to be fixed to respective sides of the fuel cell stack that comprises rigid frames adapted to be fixed on each side of the fuel cell stack and provided at its peripheries with grooves extending in the stacked direction of the fuel cell

Means for forming a seal between a fuel cell stack and manifolds to be fixed to respective sides of the fuel cell stack that comprises rigid frames adapted to be fixed on each side of the fuel cell stack and provided at its peripheries with grooves extending in the stacked direction of the fuel cell components and fastening means for uniting said frames. Each of fastening means comprises a pair of angle members each having a hook at its one end and being preassembled together with elastic washers by a clamping bolt and a nut. The hooks of the angle members of each pair is adapted to be engaged with the grooves of the adjacent frames.
