摘要:
We report a model for HT-PEMFC with the detailed description of transport processes in the cathode catalyst layer (CCL). The model is compared to our previous model, which assumed ideal oxygen and proton transport in the CCL. Calculations show that close to the oxygen channel inlet, the CCL works in the regime limited by poor proton transport, while close to the outlet, the CCL operation is determined by poor oxygen transport. The model is validated by fitting the experimental polarization curve; the CCL transport and kinetic parameters resulting from fitting are discussed.
