Abstract
The effect of carbon functionality on the electrocatalytic performance of carbon black-supported, Pt-based, direct methanol fuel cell cathod es was investigated. Polarization data show that cathodes with nitroge n and sulfur functionality have enhanced catalytic activity toward oxy gen reduction. Transmission electron microscopy results indicate that this behavior may be ascribed to a platinum particle size effect.
