Integration of Ageing in a PEMFC range extender model for on-board prognostic applications

The deployment of a FC range extender can be asuited solution to overcome the battery autonomy limitations in electrical vehicles and hybridconfigurations. In the framework of the European project Glantleap, a Polymer Electrolyte MembraneFuel Cell (PEMFC) range extender is integrated in an electrical bus to support the batteries' packload demand. The prediction of both the FC ageing and its interactions with the balance of plant(BoP) is considered as a strategical approach to anticipate and consequently reduce the FC systemperformance degradations. A PEMFC stack model has been developed using the Energetic MacroscopicRepresentation formalism. The model integrates the stack ageing laws and is adapted for on-boardprognostic and health management purposes. This paper presents shortly the model and Itsvalidation. For this purpose, the voltage losses increase with the stack ageing is presented. Toprove the model genericity, two different ageing simulationresults are proposed and compared with long-term test results. Data are referred to two differentdata-sets linked to two PEMFC stacks of the same technology, but of different generation.
