 Abstract: Background: A major issue of PEM fuel cell operation is the water management of the cells. This article tries to contribute to an improved understanding of ooding/drying out e ects by performing a analysis for a rigorous two-phase PEM fuel cell model. Method of Approach: The model is examined by means of a bifurcation analysis. This investigation is performed numerically with parameter continuation methods. The nonlinear behavior is quali ed and possible instabilities are detected. Results: A steady state multiplicity is found. The multiplicity is physically explained and the in uence of selected fuel cell parameters is investigated. The multiplicity is nally veri ed in a dynamic simulation. Conclusion: The future work aims at a model reduction of the analyzed fuel cell model to gain a low order model suitable for model-based control strategies. ©2008 American Society of Mechanical Engineers
