Effective diffusivity in partially-saturated carbon-fiber gas diffusion layers: effect of local saturation and application to macroscopic continuum models
(Elsevier B.V., 2015-11-20)Macroscopic continuum models are an essential tool to understand the complex transport phenomena that take place in gas diffusion layers (GDLs) used in polymer electrolyte fuel cells (PEFCs). Previous work has shown that ... -
Effective diffusivity in partially-saturated carbon-fiber gas diffusion layers: effect of through-plane saturation distribution
(Elsevier B.V., 2015-07)The effective diffusivity of gaseous species in partially-saturated finite-size porous media is a valuable parameter for mathematical modeling of many processes, but it is difficult to measure experimentally. In this work, ...
