| Abstract: | Because the AC impedance spectroscopy, also called as electrochemical impedance spectroscopy(EIS), can provide more detailed information than other impedance measurement methods, it becomes the most popular method for the research on the fuel cell and is being used widely in the fuel cell research field recently. The paper mainly deals with the all aspects of application in DMFC field including in-situ polarization analyst, reaction mechanism details, material performance evaluation, etc. Several key technical problems about EIS including electrochemical system establishment, the reference electrode selection, the equivalent-circuits model for analysis for spectroscopy are discussed. |
