Abstract
A two-dimensional, along-the-channel model to predict the carbon corrosion for a cathodic catalyst layer of a PEM fuel cell with a starvation zone is reported. The model is able to capture the abrupt decrease of electrolyte potential along the interface of normal and starvation zone, as reported by Reiser et al. (1). Our simulation results show that at higher operational potentials, lower protonic conductivity of the electrolyte, faster carbon corrosion kinetics and higher oxygen permeability will result in higher carbon corrosion rate.
