Proton exchange membrane fuel cell behavioral model suitable for prognostics.

International audiencePrognostics and Health Management (PHM) is a discipline that enables the estimation ofthe Remaining Useful Life (RUL) of a system and is not yet much applied to Proton ExchangeMembrane Fuel Cell PEMFC. However it could permit the definition of adequateconditions allowing extending PEMFC's too short life duration. For that purpose, a modelthat can reproduce the behavior of a PEMFC is needed. This paper presents a model of aPEMFC that could serve for a prognostics purpose. The model is composed of a static partand a dynamic parts that are independent. On one side, the static part is developed thanksto equations describing the physical phenomena and is based on the ButlereVolmer law.On the other side, the dynamic part is an electrical equivalency of physical phenomenon.The models are validated thanks to experimental data gathered in long term tests. For thatpurpose the parameters are successively updated based on characterization measurements(polarisation curves and EIS (electrochemical impedance spectroscopy)). Then theresults of the model are compared to the ageing data in order to evaluate if the model isable to reproduce the behavior of the fuel cell. The usefulness of this model for prognosticsis finally discussed
