Polymer Electrolyte Membrane (PEM) fuel cell powered vehicles are only beginning to enter
the automotive market and currently significantly more expensive than conventional vehicles. Therefore it is
important to reduce their manufacturing and maintenance costs in order to secure their position and aid with
market penetration. Improved durability and reliability of PEM fuel cells is crucial to cost reduction and can
be achieved via implementation of effective control strategies. Such control algorithms will incorporate accurate
Fault Detection and Isolation (FDI) procedures to ensure system robustness and fault tolerance. This ongoing
research project is focused on model-based FDI for fuel cells with qualitative diagnosis using Bond
Graphs (BG). BG is a graphical modelling approach which represents interactions between system components
as exchanges of energy across multiple physical domains. A bond graph model of a PEM fuel cell is introduced
in this paper and its application to FDI is considered.
