Electrocatalysts using carbon nanotubes (CNT) show higher catalytic activity as well as higher CO-tolerance in H2-O2 fuel cells. The high performance has been attributed to the interface interaction between Pt (or PtRu) catalyst particles and graphitic carbons based on surface science studies using highly oriented pyrolytic graphite (HOPG).
