Abstract

Among energy source units, batteries, supercapacitors and fuel cells are the subject of increasing interest and development for several industrial applications. In particular, they represent an important challenge in the field of transportation as an alternative to traditional fuels. As a consequence of the complexity and multiphysical nature of such devices, the characterization of their energetic behavior opens to interesting measurement aspects. In this paper, a few basic concepts related to the frequency dispersion of the electrical permittivity and to the hysteresis phenomena formation are shortly recalled, and the results of an experimental analysis performed on a supercapacitor and two fuel cells are presented.
