In this work, the experimental characterization of gas diffusion material for PEM fuel cells is carried out. Properties such as porosity, capillary pressure curves, absolute permeability, and relative permeability were obtained for carbon paper Toray-090. Experimental fixtures and procedures used to characterize the porous material are presented. The effects of PTFE treatment (wet-proofing) and compression on the porous media properties were assessed. After characterizing the porous media material, two computational models of the air-cathode of a PEM fuel cell were developed using the gas diff...
