Metal catalyst based on Pt-Ru, a fuel cell electrode, and DMFC

Provided is a Pt-Ru based quaternary metal anode catalyst for a fuel cell, in particular 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.
