Abstract
The influence of the structure and composition of the diffusion layer on polymer electrolyte fuel cell (PEFC) cathode performance was invest igated. Electrodes were prepared with different poly-tetrafluoroethyle ne (PTFE) content in the diffusion layer and maintaining a constant co mposition for the catalytic layer with a low-Pt loading (0.11 mg cm(-2 )). Electrodes were characterized by Hg-intrusion porosimetry, scannin g electron microscopy and electrochemical techniques (cyclic voltammet ry, galvanostatic polarization and ac-impedance spectroscopy).
