Abstract: A method for forming a disassembleable fuel cell assembly includes the steps of (a) forming at least two fuel cell assemblies, each of the fuel cells assemblies formed by a method including the steps of (i) providing a membrane electrode assemble and two bipolar plates; (ii) applying a first portion of a curable silicone composition to internal mating surfaces of at least one of the bipolar plates; (iii) aligning the membrane electrode assembly between the two bipolar plates; (iv) compressing the bipolar so that the first portion of the silicone composition abuts the adjacent internal mating surface of the adjacent bipolar plate; (v) curing the first portion of the silicone composition to adhesively bond the adjacent internal mating surfaces; and (vi) further compressing the bipolar plates to compress the cured first portion of the silicone composition to mechanically seal the adjacent mating surfaces against surface imperfections and/or leak paths; (vii) applying a second portion of the curable silicone comp

Abstract: A high pressure connection and method for making a high pressure connection. The method includes applying a primer composition to one distal joint portion, applying an anaerobically curable composition to the other distal joint portion; sliding one distal joint portion into the other distal joint portion and curing the anaerobic composition to maintain the second distal joint portion within the first distal joint portion thereby forming the high pressure connection. The method does not use plastic deformation of the first or second distal joint portions after the step of sliding. The method is advantageously useful for making high pressure connections in gas compression or refrigeration systems.
