The electrooxidation of methanol in an alkaline electrolyte has been studied on nickel foam-based composite electrodes. The aim of this work was to establish the electrochemical usefulness of electrodes in alkaline fuel cells. Nickel foam, exhibiting electrocatalytic activity, was modified by covering it with a polyaniline (PANI) film, followed by the electrodeposition of platinum particles on the PANI matrix (Ni|PANI|Pt). For comparison, platinum was also deposited directly on the surface of the nickel substrate. The results show that Ni|PANI|Pt electrodes exhibit the highest electrocatalytic activity for methanol oxidation in the reaction occurring in the potential range of NiOOH formation.
