In order to study dimensional effects on the performance of a PEMFC in prescence of CO impurities, 1D and 2D models were produced. The models were simulated into seven domains: membrane, flow channels for hydrogen and oxygen, each platinum catalyst layer (CL), and the Gas Diffusion Layer (GDL). This model was coupled with a 1-D inhouse electrochemical double layer model. Species concentration distribution, transport phenomena and the current density were calculated simultaneously solved over all the computational domains. Preliminary results in 1D models demonstrates performance improvement by increasing the thickness of the catalytic layer. 2D model will be carried out to analize the evolution of performance parameters.
