This chapter reports the results of an experimental analysis on a 30 kW fuel cell power train for city cars. The electric energy is generated by using a laboratory fuel cell system (FCS) based on a 20 kW H2/air PEM stack, realized taking into account the design criteria discussed in Chap. 4. The FCS experimental characterization provides results about the effect of different operative parameters on stack performance, and indications regarding the causes of energy losses associated with auxiliary components of the FCS. Moreover, reactant feeding, membrane humidification, and cooling issues are discussed, evidencing in particular the role of air compressor, fuel purge, temperature control, and humidification strategy in stack management in both steady state and dynamic conditions. The dynamic performance of the whole fuel cell traction system are tested on the European R40 driving cycle, evaluating the effect of different hybrid configurations on efficiency of single subsystems and of the overall propulsion system.
