摘要：

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