A simple, fast method for manufacturing a fuel cell separator with integrated elastomer seal has been developed using a UV-curable elastomer composition for the seal. A mold for the seal comprising a flexible sheet made of PTFE or polystyrene is employed. The mold is compressed against a separator plate between a support and a UV-transparent clamping block. Elastomer is then appropriately injected and cured using UV light. Thereafter, the flexible sheet is peeled off, rather than removed all at once, thereby avoiding delamination of the fragile seal from the separator plate.
