Editorial summary

A two-stage FLEC-based technique is proposed to estimate moisture diffusivity in hydrophilic polymer membranes while accounting for convective boundary-layer resistance and non-uniform surface transport. The procedure first determines the cell's convective mass-transfer coefficient and then combines membrane measurements with two-dimensional transport modelling.
