## Effective diffusivities in porous solids are global parameters which lump a complicated geomeuical structure together with the diffusion process. Lumping is different depending on the measurement method and this may lead to strongly biased coefficients. Three geometrical effects are studied -E
An approximate model for mass transfer with oxygen reduction in porous gas-difTusion electrodes has been enhanced to include multicomponent gaseous diffusion within the substrate. The resulting model is particularly useful in evaluating and predicting important mass transfer processes occurring in d
