Effective diffusivity and water-saturation distribution in single- and two-layer PEMFC diffusion medium

The formation–distribution of condensed water in diffusion medium of proton exchange membrane fuel cells, and its tendency to reduce the local effective mass diffusivity and to influence cell performance, are studied. First the local effective mass diffusivity of a fibrous diffusion medium is determ...
