摘要
The processes taking place in direct methanol fuel cells (DMFC) are characterized by ac impedance spectroscopy under realistic operating conditions. This method allows the separate examination of anode kinetics, anode mass transport, cathode kinetics, cathode mass transport, and membrane conductivity, making it a valuable diagnostic tool for DMFC development.
