Abstract

"An ordered arrangement of carbon nanotubes (CNTs) on which Pt nanoparticles are supported and coated with Nafion film is proposed as a nanostructured catalyst layer for Polymer Electrolyte Membrane (PEM) fuel Cells. Specifically, the study is focused on the cathode catalyst layer of the fuel cell electrodes. The catalyst layer is mathematically modeled, taking into consideration multicomponent and Knudsen diffusion in the gas phase. To account for binary diffusion, a Slattery-Bird correlation is used to obtain the effective diffusion coefficients. The electrochemical reaction kinetics is assumed to follow a first order Volmer-Butler mechanism. Henry's law is used for the interfacial equilibrium"--Abstract, page iv.
