CONCLUSIONS:

CO tolerance and methanol oxidation studies on single phase smooth electrodes, as well as methanol oxidation studies on dispersed fuel cell electrodes indicate that bifunctional ternary catalyst in the Pt-Ru-Os system is superior to binary Pt-Ru catalyst for DMFC anode. A rational methodology is presented for the development of improved DMFC anode catalyst.
