Effect of Different Support Morphologies and Pt Particle Sizes in Electrocatalysts for Fuel Cell Applications
Figure 5
SEM images of the MEA with Pt/MWCNT ((a) and (b); cross-section and top view) and the MEA with Pt/MCMB cathode ((c) and (d); cross-section and top view); the cathode is the electrode on top in the cross-sectional views. The top view reveals the very dense structure of the Pt/MCMB cathode in contrast to the more “fluffy” appearance of the MWNT electrode.
