Nano-electrochemical deposition of fuel cells electrocatalysts

Abstract

The paper reports on the development of automated electrochemical deposition method as a synthetic strategy for fabrication of catalytically-active thin-films (or nanostructured) materials, composed of platinum Group Metals (PGMs), with potential technological applications in fuel cell eclectrodes. The paper demonstrates the versatility of part-by-part (sequential) electrodeposition of binary alloys composed of Platinum and Ruthenium, to produce catalytic-active layers on an inert carbon substrate, whereby such fabricated bimetallic systems exhibit superior activity towards oxidation of methanol, a typical fuel used in Direct Methanol Fuel Cell as compared to the pure platinum catalysts
