In order to produce useful electrocatalysts for low-temperature fuel cells, significant efforts have been made worldwide on developing Pt-based catalysts with low Pt contents as well as searching for alternative materials with high catalytic activity for anodic and cathodic reactions. In the case of anode materials, our proposed new method consists of the synthesis of Pt-based nanoparticles in order to maximize their surface availability, combined with the use of secondary metals that promote the oxidations of methanol and CO. On the other hand, for the cathode materials, the use of the Pt catalysts mixed with metal oxides enhances their oxygen reduction reaction (ORR) activity. We anticipate that the highly dispersed Pt based nanoparticles will improve the performance of anode and cathode for low-temperature fuel cells. |
