Oxygen transport resistance correlated to liquid water saturation in the gas diffusion layer of PEM fuel cells

Under typical proton exchange membrane fuel cell (PEMFC) operating conditions, temperature gradients through the porous gas diffusion layer (GDL) can result in product water condensation. As a result, non-uniform partial saturation of the GDL changes the local effective porosity and tortuosity encou...
