✦ Synopsis

The voltage dynamic properties of PEM fuel cell stack have been analyzed through experimental investigation. Different behaviours between voltage overshoot and undershoot are found under load commutations. A semi-empirical dynamic model for stack voltage is introduced on the basis of experimental investigation. The proposed model can predict the transient response of stack voltage under step change in current. Comparing with previous model, the suggested model indicates a better agreement between tests and simulations.

## Abstract In designing and controlling fuel cell systems, it is advantageous to have models which predict fuel cell behaviour in steady‐state as well as in dynamic operation. This work examines the use of electro‐chemical impedance spectroscopy (EIS) for characterising and developing an impedance

This work presents a control strategy for PEM fuel cell systems based on simultaneous impedance measurements on single cells. This control strategy distinguishes between flooding and drying of the cells in a stack and helps to run the stack at an optimal operating point. In the presented experiments
