A kinetics of formic acid anodic oxidation at electrodes consisting from composites of platinum and palladium with polyelectrolytes is studied. Various polyelectrolytes studied have different functional groups. The composites were prepared via ionic exchange, and were supported at single walled carbon nanotubes. The following polyelectrolytes were studied: polydiallyldimethylammonium chloride (PDDA), polyethylene imine (PEI), polystirene sulfonic acid (PSS) and polyacrylic acid (PAA). It was found that introduction of polyelectrolytes does not results in principal alteration of anodic process mechanism, but effects upon rated of separate parallel steps. The composites of Pt with PDDA and Pd with PSS were happen to be the most active.
