Abstrak

A new technique, which was developed to characterize the direct methanol fuel cell under work conditions, has been presented in this paper. The impedance measurements were made using dynamic electrochemical impedance spectroscopy research technique in the galvanostatic mode, using multiple sinusoidal excitation. Obtained results show, that together with an increase of the temperature and working load, the global impedance of the cell decreases. However the value of methanol flow rate does not have any influence on the impedance value. Current-voltage characteristics were also obtained.
