Abstract

See full text

A first transport system moves a web comprising a subgasketed CCM layer and an application system applies a crosslinkable resin to at least a subgasketed portion of the subgasketed CCM layer. The crosslinkable resin preferably comprises a photocurable cationic crosslinkable resin. A first curing apparatus subjects an exposed surface of the crosslinkable resin to a photo curing process to initiate curing of the crosslinkable resin. A second transport system moves a GDL into adhering contact with a partially cured exposed surface of the crosslinkable resin of the CCM layer so as to form an MEA layer. A second curing apparatus subjects the GDL, partially cured crosslinkable resin, and CCM layer structure to a thermal curing process to substantially complete curing of the crosslinkable resin. A converting system is configured to receive the MEA layer and produce a plurality of discrete MEAs from the MEA layer.
