In the last decades, polymeric membrane-based fuel cells (PEMFC) have been extensively studied. However, despite a great scientific effort, there are still some aspects of fuel cell operation that are difficult to access from an experimental point of view, as is the case of the so-called three-phase zone. In this work, we use Molecular Dynamics simulations and electrochemical experiments on a Nafion/Pt/C system to evaluate the effect of Nafion content and hydration level on the Electrochemical Area (ECSA) in the PEMFC.
