2 Performance of Carbon Nanotubes and Nanofibers Membrane Electrode Assembly 

Yan and co-workers [65] conducted polarization curve measurement in a PEM fuel cell with CNT-based electrodes. They found an improved polarization behavior for the CNT-based MEA throughout the whole potential range compared to the conventional Pt/C MEA. In activation controlled regions, the measured current density for the CNT-based electrode is higher than that of the conventional electrode (e.g., 153 mA/cm vs. 98 mA/cm at potential of 0.8 V), indicating that
