Provided is a Pt-Ru based quaternary metal anode catalyst for a direct methanol
fuel cell (DMFC). The Pt-Ru based quaternary metal anode catalyst has high activity
to methanol oxidation and strong resistance to catalyst poisoning due to carbon
monoxide (CO), which is a byproduct of the methanol oxidation. Therefore, the Pt-Ru
based quaternary metal anode catalyst can give high power density and can replace
existing commercial catalysts.
