The oxidation of methanol in an alkaline medium on bimetallic catalysts
Oxidn. of MeOH was studied on foamed Ni-based Pt-Ru electrodes in 6 M KOH contg. 0.3 M CH3OH to assess their usefullness for alk. fuel cells. In the 1st cycle, the electrocatalytic activities toward MeOH oxidn. at low potentials followed the descending order: Ni/(4:2)Pt-Ru > Ni/Pt > Ni/(4:1) Pt-Ru > Ni/(4:3)Pt-Ru > Ni. In subsequent cycles, the activity of the Ni/Pt decreased, whereas that of the Ni/Pt-Ru electrodes rose.
