Both the activation and the mass transport losses
exhibit a non-linear behavior. The research provided in Refs. [20,21]
discusses electrochemical/electroanalytical techniques employed in the
experimental study of MFC presenting and discussing these techniques.
In the example provided in Ref. [22] a power management system is
proposed with the main goal of at first store the energy provided by the
MFC and next power the wireless device. Details about experimental
methods to study and evaluate the performance of MFCs are presented in
Refs. [23–25].
