Bead-Type Separator for Fuel Cell and Assembly Thereof

A bead-type separator for a fuel cell includes a reaction surface disposed at a center of the separator and for reacting a flowing reaction gas, a diffusion part disposed at both sides of the reaction surface for diffusing the reaction gas, multiple manifold through-holes disposed in regions at both ends of the separator and introducing or discharging the reaction gas, and multiple protruding inner bead seals along a periphery of the regions in which the manifold through-holes are disposed, wherein the inner bead seals comprise a first inner bead seal disposed at the periphery of the region in which the manifold through-hole configured to discharge the reaction gas is formed, and wherein the first inner bead seal includes multiple main discharge bead flow fields protruding in tunnel shapes from a diffusion part and multiple main connection bead flow fields.
