A model for carbon and Ru corrosion in a DMFC anode under strong methanol depletion is developed. The model is based on current conservation equation in the membrane. In the methanol-depleted domain, methanol oxidation reaction is substituted by the carbon oxidation (corrosion). This dramatically lowers the membrane potential and creates an environment for electrochemical oxidation of Ru. Calculations show that 50-100 mV loss in the cell potential manifests quite a significant (above 50%) methanol-depleted fraction of the cell active area. (C) 2011 Elsevier Ltd. All rights reserved.
