New carbon supports with improved electrochemical resistance for proton exchange membrane fuel cells

摘要

In the present study the effect of the modification of commercial carbon black KetjenBlack DJ-600 (KB) with nitrogen-containing compounds and pyrocarbon for improving their corrosion stability has been investigated. The modification with nitrogen-containing compounds has been carried out by decomposition of acetonitrile (AKB) and pyridine (PKB) vapors over the support surface. The modification with pyrocarbon has been carried out by decomposition of methane (MKB).
