Na. Mayorova et al., METHANOL ELECTROOXIDATION ON PLATINUM MESH ELECTRODES BONDED TO SOLIDPOLYMER ELECTROLYTES, JOURNAL OF SOLID STATE ELECTROCHEMISTRY, 2(4), 1998, pp. 262-265
Methanol electrooxidation on smooth platinum electrodes bonded to soli
d polymer electrolytes was studied in water and acid solution by volta
mmetric measurements with different scanning rates. An enhancement of
the oxidation rates was observed in these systems as compared to ident
ical platinum electrodes in contact with liquid electrolytes. This ele
ctrocatalytic effect strongly depends on the measuring conditions and
on the electrode potential. The reasons for the catalytic effects at d
ifferent potentials are discussed.
