POLYMERIZABLE COMPOSITIONS FOR BONDING AND SEALING LOW SURFACE ENERGY SUBSTRATES FOR FUEL CELLS

摘要

An electrochemical cell (10) having improved sealing against leakage includes a cured sealant composition (40) adhesively bonded to the mating surface of components in the cell (10). The cured sealant composition includes reaction products of a polymerizable (meth)acrylate component and a boron-containing initiator. Such a sealant composition is particularly useful as an adhesive for plastic or plastic containing substrates disposed in the electrochemical cell (10).
