Information

The default surface tension (γ = 0.0663 N/m) is for saturated water at 60 °C, interpolated from [Incropera2002, pp. 924]. Note that the surface tension in [Wang2001] is incorrect (likely unit conversion error).

The default permeability (κ = 6.46×10^-5 mm²) is based on the air permeability of SGL Carbon Group Sigracet® 10 BA [SGL2007]. Wang et al. use κ = 10^-5 mm² [Wang2001].

The default contact angle (θ = 140°) is typical of the GDL measurements listed at http://www.chem.mtu.edu/cnlm/research/Movement_of_Water-in_Fuel_Cell_Electrodes.htm (accessed Nov. 22, 2103).
