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
