In this program, funding has been provided to a project aiming to federate all the French competencies around fuel cell systems. Thus, as a first achievement, a review on existing modelling methodologies for PEM fuel cell systems is here proposed. 1. INTRODUCTION In the framework of the “Energy program” of the French National Centre for Scientific Research (CNRS), funding has been provided to a project aiming to federate all the French competencies around fuel cell systems. A working group on this topic has also been set up. Nevertheless and before all, the first question is what is a “fuel cell system”? Figure 1 presents a general scheme of such a generic fuel cell system. As it can be seen, a fuel cell stack needs a lot of ancillaries to be operated. The fuel must firstly be produced and/or stored. Then, it is finally processed (mostly in terms of pressure, hydration and flow regulation) before entering the fuel cell stack. The oxidant must also be processed in the same way. For both fuel and oxidant gases, the water produced by the FC stack can be removed from the exhaust gases to be re-used in the
