Abstract: Shaped microporous articles are produced from polyvinylidene fluoride (PVDF) and nucleating agents using thermally induced phase separation (TIPS) processes. The shaped microporous article is oriented in at least one direction at a stretch ratio of at least approximately 1.1 to 1.0. The shaped article may also comprise a diluent, glyceryl triacetate. The shaped microporous article may also have the micropores filled with a sufficient quantity of ion conducting electrolyte to allow the membrane to function as an ion conductive membrane. The method of making a microporous article comprises the steps of melt blending polyvinylidene fluoride, nucleating agent and glyceryl triacetate; forming a shaped article of the mixture; cooling the shaped article to cause crystallization of the polyvinylidene fluoride and phase separation of the polyvinylidene fluoride and glyceryl triacetate; and stretching the shaped article in at least one direction at a stretch ratio of at least approximately 1.1 to 1.0.

Abstract: 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.
