Abstract
The corrosion-resistance of a carbon nanocage used as a catalyst support in a polymer electrolyte membrane fuel cell was investigated by measuring CO(2) generation using on-line mass spectrometry at a constant potential of 1.4 V for 30 min. Polarization curves of membrane electrode assemblies containing Pt/carbon nanocage were obtained and used to evaluate performance degradation. The carbon nanocage was found to possess significant resistance to electrochemical corrosion, exhibiting low performance degradation of only about 2.3% after the corrosion test. This high corrosion resistance is attributed both to the strong hydrophobic nature of the surface and the graphitic structure of the carbon nanocage.
