Carbon Materials Used for Electrocatalyst of Polymer Electrolyte Fuel Cells

Abstract

The polymer electrolyte fuel cell (PEFC) has recently received much attentions because of the several advantages it offers for transportation, stationary and portable applications. This paper reviews carbon materials used for electrocatalyst of PEFC. The effects of carbon support on the functions of electrocatalyst are shown, which gov e r n the performance of PEFC. New carbons such as nanotubes are also discussed as a candidate for novel catalyst suppo r t .
