Pt catalysts are investigated for methanol oxidation in direct fuel cells, utilizing the electrochemical quartz microbalance method (EQCM) with exceptional resolution and sensitivity. were deposited onto gas-diffusion layer of carbon using stationary potential electrodeposition. Physical characterization tests performed. SEM results showed that presented dendrite crystals nanoscale facets. Cyclic voltammetry (CV) demonstrated current density reaction highly reached 1020 mA·cm−2 catalyst by EQCM. The crystal structures provide much area high catalytic activity. It found peak decreased after five cycles. Furthermore, response frequency adsorption was EQCM compared commercial PtRu catalysts. more rapidly than is possible small organic molecules on to occur during electro-oxidation COad intermediates. mechanism preliminarily discussed measurement combined
