SEALANT INTEGRATED FUEL CELL COMPONENTS AND METHODS AND SYSTEMS FOR PRODUCING THE SAME

摘要

A fuel cell, having improved sealing against leakage, includes a sealant disposed over the peripheral portions a membrane electrode assembly such that the cured sealant penetrates a gas diffusion layer of the membrane electrode assembly. The sealant is applied through liquid injection molding techniques to form cured sealant composition at the peripheral potions of the membrane electrode assembly. The sealant may be thermally cured at low temperatures, for example 130° C or less, or may be cured at room temperature through the application of actinic radiation.
