Application of Conducting Polymers/Metal Composites for C1 Molecules Electrooxidation

Low-temperature fuel cells as new-style energy devices have attracted great attention because of their high-energy conversion efficiency,low operating temperature,low pollutant emission,the simplicity of handling liquid fuel and quick startup.High efficient electrochemical oxidation of small organic molecules will be directly related to the development and application of low-temperature fuel cells.The current state of the art employs carbon-supported platinum and platinum alloys as anode and cathode catalysts in low-temperature fuel cells.However,carbon material may cause easily Pt particle aggregation and carbon corrosion occurred by electrochemical oxidation,which lower the utilization rate of Pt and the lifetime of fuel cell.CPs have attracted great attention because of their advantages of high anti corrosion,low resistance and high stability.In this paper,we illustrate the recent research progress of some CPs / metal composites proposed as electrode materials for fuel cells.
