ABSTRACT:
Acidic groups such as those in the sulfonic acid family have been successfully linked onto the surface of carbon used as catalyst support. Electrodes made using such sulfonated catalysts as used in electrochemical cells improve the performance of the cells, more so than cells fabricated from electrodes using an unsulfonated electrode.
