This study investigates the influence of the catalyst (Palladium, Pd) mass that loaded onto a glassy carbon electrode (GCE) on the catalytic activity of methanol (MEO), formic acid (FAEO), and ethylene glycol (EGEO) electro-oxidation, the corresponding principal anodic reactions in the direct methanol (DMFCs), formic acid (DFAFCs), and ethylene glycol (DEGFCs) fuel cells, respectively. By increasing the Pd loading at 0.1 V, the Pd surface area increased from 0.55 cm2 (2 min Pd deposition) to 1.94 cm2 (25 min Pd deposition) which increased the peak currents (IP) of MEO (from 0.181 to 0.608 mA), FAEO (from 0.236 to …
