Hybrid Ageing Model of a Proton Exchange Membrane Fuel Cell (PEMFC)

Today the world is full of time-dependent phenomena in all fields: physics, chemistry, mechanics and many others. Time acts on performance any system whatever its nature is. When a operates over time, aging becomes real concern. Regarding fuel cells, several degradation can occur short or long term. Short-term are generally referred to as reversible degradations, these degradations order microsecond go up hours sometimes days, such problems related water management. The term usually called irreversible degradations; it be defined aging. This phenomenon day increase months. In mitigate impact cell performance, good corrective actions must taken. To do so, prediction during conducted. this paper verified tested prognosis approach applicable cells presented. novelty used linked modular structure. fact, has three phases. first one aims identify internal physical parameters stack using an optimization algorithm experimental data static model. second predicts temporal evolution algorithm. Finally, reconstruction phase consists that re-injected into model reconstruct polarization curves thus reflect cell. reliability repeatability proposed have been successfully validated two sets from different campaigns.
