Abstract

Polymer fuel cell electrode growth using vapor deposition techniques is reviewed. The supports, the nanocatalyst sizes and morphologies, and the resulting electrodes are examined as a function of the vapor deposition process; sputtering, CVD, plasma-enhanced (PE)CVD, and metal-organic (MO)CVD. In each case, up-to-date fuel cell performances are highlighted. Vapor depositions are valuable techniques for designing fuel cell electrodes of various kinds with good fuel cell performances, e.g., power density and catalyst activity
