High surface area carbon supported PtPdSn for methyl formate, methanol and formic acid oxidation

P
roton exchange membrane fuel cells have been investigated as an alternative power source for portable electronic
devices and electric vehicles utilizing mainly hydrogen or small organic molecules (SOM) as fuel source and
oxygen form air as an oxidant, at the anode and cathode respectively. The advantages of this type of fuel cells are
high energy conversion efficiency directly to electricity and low operation temperatures. The slow kinetics of fuel
oxidation (i.e. methanol, ethanol etc.) is the major obstacle for the commercialization of fuel cell technology based
on these fuels, in addition to the high price of Pt and Pd based catalyst typically used in the anode. An addition of
oxophilic second or third atom, such as Ru, Sn, Ni, etc., to Pt or Pd improves the catalytic activity and tolerance
towards the presence of poisoning species during the oxidation of SOM. Carbon materials are commonly used
as support materials due to their good electronic conductivity and high specific surface area that influences the
properties of the catalyst, such as, charge transfer and improved dispersity of the catalyst particles. This leads to
the increase in the utilization of the precious metal constituent. Ternary catalyst (Pt

) supported on different
carbon materials with different surface area (Vulcan CX72, Multi Walled Carbon Nanotubes and Black Pearl 2000
carbon) have been studied for electro-oxidation of methanol, formic acid and methyl formate. The electrochemical
result shows that the MWCNT supported PtPdSn catalyst exhibits higher electro-oxidation current of methanol,
methyl formate and formic acid compared to PtPdSn/XC72 and PtPdSn/BP2000.
Biography
Svetlana Lyssenko is a Master student in Fuel cell and Electrochemistry group, Ariel University, Israel under the supervision of Prof Alex Schechter. The key
findings of her research work are to study the high surface area carbon supported platinum-based anode catalysts for methanol, methyl formate and formic acid
