This paper presents a method for modeling a PEMFC by using electrical circuits. In particular, it focuses on temperature and voltage distribution of fuel cell. The current distribution is calculated by using the Newton-Raphson method in order to estimate the physical parameters (connection resistances) of the model. Several test on a single PEMFC cell have been carried out during this study. In order to validate the model, temperature and voltage sensors have been installed in different segments of a single cell. A distinguishing advantage of the developed model is its ability to detect and localize the faults within the PEMFC cell, as well as simulate different faults in all of the three directions of the PEMFC cell. •A new approach for fault detection is presented.•The model taking into account the geometrical directions of the single PEMFC.•The NRM is used in order to calculate the current density distribution.•Voltage measurement are carried out in different segments of PEMFC.•Experimental data of variation voltage/temperature distribution are implemented.
