| Abstract | Direct formic acid fuel cell (DFAFC) system with hydrogen peroxide (H2O2) used instead of oxygen as cathode oxidant for marine applications was investigated. Cell performance of DFAFC system was studied on various types of metal (M): Ir, Mo, Co, Ag, W, Ni, Sn of Pt-M binary metal alloy at anode side. The anode catalysts were prepared by using an airbrush painting method. Performance characteristics of DFAFC system such as electrical and thermal power and cell potential were also studied and compared between experiment and computation by using DFAFC stack model.The 15%Pt-15%Sn/C catalyst yielded 17% lower catalytic activity for the formic acid oxidation reaction than the 20%Pt-10%Ru/C commercial catalyst but gave higher open circuit voltage. In addition, the price of 15%Pt-15%Sn/C was about 50% cheaper than the 20%Pt-10%Ru/C commercial catalyst. The polarization curve of experimental results was compared to computational results. A good agreement is found between experiment data and computation. |
