RATE-LIMITING STEPS ON FUEL-CELL ELECTRODES
Abstract
The purpose of this investigation was to identify and to study the step or steps that limit fuel cell electrode performance. The electrodes considered were the typical porous, gaseous diffusion type, and most of the effort was directed toward acquiring a more quantitative understanding of the effect of the different variables governing electrode performance. Since it is necessary to be able to predict quantitatively both the mass transfer and the kinetic limitations in order to calculate electrode performances, an experimental program directed toward obtaining the necessary kinetic data for systems of interest was undertaken. An experimental system was devised by means of which the electro chemical kinetics could be studied over a wide current density range independently of mass transfer effects, on electrodes of known catalyst area. In the operating region where the effect of mass transfer became significant, it was le quantitatively to assess its importance.
