Proton Exchange Membrane Fuel Cells (PEMFCs) are in an advanced state of development. However, the weight, volume, and cost of this type of systems are still limiting factors to their commercialization. In order to overcome some of these constraints, work has been conducted to attain high performances in hydrogen/air PEMFC, working at atmospheric pressure. The electrodes were prepared by either the spray or the dry method, and contained a platinum loading varying between 2 and 6 mg/cm2. The

The optimization of the composition and structure of the electrode catalyst layer led to performance such as 0.35 W/cm2 at cell voltage of 0.7 V.
