Fig. 5: Hydrogen-air fuel cell performance evaluation.
From: An integrated platinum-nanocarbon electrocatalyst for efficient oxygen reduction
a LSV curves of different catalysts; inset a is an enlarged view of 0.7−1.0 V, b LSV curves of Pt/C and PtCo@CoNC/NTG before and after ADTs, and c I-t curve of PtCo@CoNC/NTG at 0.6 V vs. RHE in the GDE evaluation. d Fuel cell polarization plots of different cathode catalysts, e fuel cell stability test at a voltage of 0.6 V, and f performance comparison of recent carbon supported electrocatalysts in hydrogen-air fuel cells (references corresponding to data points are listed in Supplementary Table 4).
