Description One of the major contributors to the ohmic loss in fuel cells originates at the interface between adjacent cell components. The compressive pressure used to achieve contact in cells should be carefully estimated to ensure that resistive losses arising from contact behavior remain minimal. In present work, a generic model is developed, capable of estimating contact resistance as a function contact pressure at the interface of graphite bipolar plate and carbon fiber based gas diffusion layer at different temperatures. A good agreement is observed between the results obtained from the model and experiments. Compressive pressure in the ranges of 3-4 MPa is found optimum for achieving low contact resistance. The contact resistance obtained for carbon paper and BPP while using recommended pressure lies between similar to 9 and 4 m Omega cm(2) considering the operating regime of HT-PEMFC (120-180 degrees C). Operating under similar conditions, the contact resistance values for carbon cloth and BPP is similar to 13 to 7 m Omega cm(2). Copyright (C) 2013, Hydrogen Energy Publications, LLC.
