Résumé

To improve Proton Exchange Membrane Fuel Cells (PEMFC), it is necessary to understand the phenomena occurring in operating conditions. The objective of this study is to determine how carbon support architecture can impact PEMFC performances, particularly diffusive limitations. In this context, as they have a controllable texture, carbon aerogels were used as catalyst supports in PEM fuel cell cathodes. Three carbon aerogels with different morphologies were synthesized. Fuel cell measurements show that the carbon support architecture has a significant impact on diffusive limitations. Moreover, they confirm that Nafion® loading must be optimized in order to preserve the catalytic layers architecture. This work finally highlights the impact of the catalytic layers architecture on the PEMFC performances.
