Platinum-based anode catalyst dispersed in polyaniline for the direct methanol fuel cell

摘要

Polymer electrolyte fuel cell anodes containing noble metals, including either Pt, Pt-Ru, or Pt and Sn particles were dispersed in a thin film of polyaniline (PAni) on carbon cloth and tested as anodic material in a direct methanol fuel cell and polarization curves were recorded. Even if the performance of these anodes remained in general inferior to that of conventional electrodes, the curves obtained with Pt-Sn/PAni were encouraging, at least at low current densities.
