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).
