Abstract: With increasing use of renewable energies, such as photovoltaic, wind, biomass, thermosolar,\ngeologic, appeared the challenge of the storage. If it is talking about the mobile devises,\nit is easy to see that it is necessary store this energy to use it later. In the case of the\nvehicles the need is obvious to change the oil engine to electric engine, but this happens in\nall mobile devices. The polymer electrolyte fuel cells (PEFC) convert hydrogen and oxygen\nto electricity. The energy is store as hydrogen gas and the waste is water. Nowadays, there\nare lots of companies studying the viability of these systems. The future of these batteries\npass through the good relation between the performance and the price. A signi cant fraction\nof the PEMFC cost is focused on the electrodes, exactly in the catalyst used. This catalyst\nis platinum and it has an important cost comparative with the other parts of the fuel cell\n[1].\nThe present thesis studies the e ect of Pt loading in the electrode of proton exchange\nmembrane hydrogen fuel cells (PEMFCs). Gasteiger, Panels and Yan study showed that\nthe anode Pt loading doesn't signi cantly a ect the performance of hydrogen fuel cells [2].\nHowever, in the present study di erent experiments with catalyst-coated membranes (CCM)1\ncorroborated what it was known before about the cathode loading. But in the case of\nthe anode loading, it was proved that there is an optimum loading which gives the best\nperformance. This results will reduce the costs of the PEMFC at least in the anode side.
