The AMESSeal Form-in-Place gasketing system for Fuel Cell components

Fuel Cell stack, Membrane Electrode Assembly (MEA), and Bipolar Plate manufacturers face the dual challenge of improving sealing performance and durability, while reducing costs. The AMESSeal liquid delivery system automatically dispenses and bonds a thin bead of low-durometer elastomers directly onto metal, graphite or polymer substrates, thereby cutting in half the possible sources of leakage, compared to traditional die-cut , mold-in-place, or molded gaskets. Our patent pending process for applying multiple layers of elastomers allows us the means to adapt our process to meet our customers’ specific sealing needs. A typical multilayer gasket would combine the compliance and sealing of silicone, with the improved chemical and temperature resistance and durability of a fluoroelastomer.

The programmable liquid delivery system applies gaskets in an infinite number of complex patterns, without the high upfront tooling and/or mold costs associated with die-cut or molded gaskets. In addition, gasket costs are further reduced through the elimination of material waste and lowering of gasket assembly costs.
