The performance of a proton exchange membrane (PEM) fuel cell is limited by electrochemical kinetics, proton conductance through the ionomeric material, and mass transport limitations. The electrochemical reaction itself takes place within the porous catalyst layer at the three-phase boundary on the surface of a platinum catalyst. A detailed one-dimensional model was developed to study the material and structural properties of the membrane, catalyst layer, and gas diffusion layer (GDL) of Gore PRIMEA® membrane electrode assemblies (MEAs). The focus of this paper is the application of the model to study the catalyst layer of a PEM fuel cell.
