Carbon black remains the most widespread support to prepare catalytic layers of Proton Exchange Membrane Fuel Cells (PEMFCs). The composition and the pore texture of these carbons are key variables to the device performance, through (i) the ability of the support to disperse metals, (ii) the electrolyte/carbon contact and (iii) the reactant/product mass transport within the porosity [1]. However, in the case of carbon black, the pore texture of the final electrode is not controllable since it largely depends on its processing, and not on the material itself.
