The electrospray deposition (ESD) of platinum supported on carbon (Pt/C) particles has been used for the preparation of electrodes for proton exchange membrane fuel cell (PEMFC). Catalyst layers with platinum loading ranging from 0.2 mgpt/cm2 down to 0.025 mgpt/cm2 and different Nafion® contents were obtained by ESD method. Morphological studies of the catalyst layers by scanning electron microscope (SEM) inspection showed fractal structures with a high dispersion of catalyst. In this paper, the morphology, SEM, IV-curve compared each platinum loading range 0.2 – 0.025 mgpt/cm2. |
