Proton exchange membrane fuel cell (PEMFC) is a promising power source for automobiles in the near future. During operation, there are gases and liquids inside the fuel cell. Sealing around the perimeter of the cell is therefore required to prevent the gases/liquids inside the cell from leaking. Polymers are usually used as the sealing or gasket materials. They in general possess the property of viscoelasticity. The stress relaxation behavior of a polymer, liquid silicone rubber, is studied in this article. Applying the time-temperature superposition, master curve is generated for the prediction of service life of this material used as seals in PEMFC.
