ABSTRACT: In this paper, the dynamic
mathematical model of a proton exchange membrane (PEM) fuel cell is presented.
Dynamic performance of a PEM fuel cell system by experimental and simulation
using matlab/simulink is investigated. The
V-I load characteristics of a 1.2 kW PEM fuel cell are presented. Result shows that the starting current of the PEM fuel cell operated at
rated load reaches to approximately twice of its rated current in just less
than 0.015 second before it reached to its steady state condition. Step change load responses of this PEM
fuel cell were experimented and simulated. It was found out, from the results
obtained, that PEM fuel cell had a very fast response to load changes.
Moreover, results show that the experimental and the result computed by using the simulation of the model are
very close to each other which validates the model. Hence, this model could be used to implement a controller design
in order to come up with an optimal and efficient operation of PEM fuel cell. Based also on the results, a suitable power
conditioning can be constructed and designed for safe and reliable operation
of PEM fuel cell especially in integrating and connecting it to a hybrid wind/PV
distributed generation system.
