    • A fuel cell, having improved sealing against leakage, includes a fuel cell component having a cured sealant, wherein the cured sealant includes a telechelic-functional polyisobutylene, an organhydrogenosilane crosslinker, a platinum catalyst and a photoinitiator. The fuel cell component may be a cathode flow field plate, an anode flow field plate, a resin frame, a gas diffusion layer, an anode catalyst layer, a cathode catalyst layer, a membrane electrolyte, a membrane-electrode-assembly frame, and combinations thereof. A method for forming such a fuel cell includes the steps of providing a fuel cell component including a substrate; providing a mold having a cavity; positioning the mold so that the cavity is in fluid communication with the substrate; applying a curable liquid sealant composition into the cavity, wherein the curable sealant composition includes a telechelic-functional polyisobutylene, an organhydrogenosilane crosslinker, a platinum catalyst and a photoinitiator; and curing the composition with actinic radiation.

    • Allylic styrene ether compounds of the formula: ##STR1## where R.sup.1 is an optionally substituted allylic or propargyl hydrocarbon group, and R.sup.2, R.sup.3, and R.sup.4 are independently H, C.sub.1-6 hydrocarbon or C.sub.1-6 hydrocarbonoxy groups, are prepared in a single pot reaction from relatively low cost materials. The method includes the steps of reacting a 4-acyloxystyrene of the formula ##STR2## where R is an acyl group, with at least one mole of a base which can readily saponify or hydrolyze the phenolic ester bond per mole of acyloxystyrene, and then adding to the reaction mixture an alloylating agent of the formula R.sup.1 X, where R.sup.1 is as previously defined and X is chloride, bromide, iodide, a sulfonic ester or a hydrocarbon sulfate group, to form said allylic styrene ether compound. The method may be employed to prepare mono-styryl functional compounds or di-styryl functional compounds such as 1,4-bis(4'-vinylphenoxy)but-2-ene.
